Fuse 1.6.0 for OpenDingux/RetroFW
=================================
This port is a compilation of Fuse 1.6.0 for Opendingux/RetroFW with some
additions to the Fuse SDL UI and some new options for this devices.
So the thanks for this port are for Phillip Kendall and the Fuse team.
And also to the GCW0/OpenDingux and RetroFW community for all documentation,
development threads, and all the opensource ports.
At the end of this doc is the man page of Fuse 1.6.0 for a complete
reference.
Using the Fuse emulator
=======================
------------------------
### Opening the Menu ###
------------------------
You can open the menu with the `Power` or `Select` button.
If `Select` button is mapped to joystick or keyboard then the only
option to open menu will be `Power` button.
---------------------
### Save settings ###
---------------------
By default the emulator don't save settings changes. You can save
settings at any time from menu: `Menu -> Options -> Save`.
You also can activate "Auto-save" to save settings when you exit the
emulator.
|To activate auto-save access to `Menu -> Options -> General` and
|check 'Auto-save settings'.
|Check the option with the `X` button and accept options with the `A`
|button.
|You should exit from Fuse or use the 'Save' option to save the
|changes.
In this port the options are saved into 'fuse.cfg' file in the fuse
config path.
If some option changes prevent to open the emulator delete this file
and try to start again.
The config path is in '$HOME/.fuse' directory. If it does not exist
then Fuse will create it at start.
|$HOME is located in:
| - OpenDingux: '/media/data/local/home'
| - RetroFW: '/home/retrofw'
----------------------------------
### OpenDingux/RetroFW options ###
----------------------------------
For the OpenDingux/RetroFW port some additional options had been added.
Savestate options
-----------------
The Savestates functionality is a layer for quickly saving and loading
snapshots organized by machine models and program names.
Internally it uses the main functionality of Fuse to read and write
snapshots.
Becouse the main objective is speed up the operation to read
and write snapshots for the use with handelds the options for
savestates has been put directly in the main menú and assigned to new
kotkey combos.
Hotkeys assigned for savestates:
· L1 + Cursor down Quicksave state for current slot
· R1 + Cursor up Quickload state for current slot
· R1 + Cursor right Increase slot to use
· R1 + Cursor left Decrease slot to use
- Current slot
------------
Default 0. Maximum 99.
Current number of slot used for quick saves and load.
The slot number for savestates is global. If you load another program
without exit the emulator, the slot in use for the savestates of the
newly loaded program is the one previously used.
- Show slot in status bar
-----------------------
Default enabled.
Show the current selected slot in status bar info.
- Savestates format
-----------------
SZX, Z80. Default SZX.
Format used for the savestates.
The default SZX is the recommeneded format. For Z80 format a warning
about loss of information will be emmited.
The Z80 format does not support all combinations for storing information
about the media and hardware used, this include same machine models.
Some examples:
· Pentagon 256 and 1024 are saved as Pentagon 128, so when you save
a savestate with this models the load change to Pentagon 128. If you
are using savestates per machine model then the path to access
savestates also change.
· If you are using interface 2 with cartridge this information is lost
when saved so the load of savestates will fail.
For a tipical media as tapes and disks with no extra hardware attached to
emulator you can go ahead with Z80 format, but for best cominations of
hardware and media it's best to stick with SZX format.
For Z80 format see https://worldofspectrum.org/faq/reference/z80format.htm
For SZF format see https://www.spectaculator.com/docs/zx-state/intro.shtml
- Savestates per machine model
----------------------------
Default enabled.
By default the savestates use different locations for every model.
This behaviour can be changed disabling this option but that can lead
to strange situations. For example:
· load a program for a 48k model
· Create a savestate
· Change the model to +2A and load again the same program
· Load the savestate and the machine model is restored to the 48k model
* Savestates location is:
$HOME/.fuse/savestates/<MODEL>/<PROGRAM NAME>
$HOME/.fuse/savestates/<PROGRAM NAME> if disabled per machine model
· <MODEL> is the name for machine model as informed by libspectrum.
· <PROGRAM NAME> is the name of the program with an attempt to remove
any info about side/disk/part.
· The name for the savestate will be the slot number with the extension
for the format configurated.
* For mediums with various parts (disk and tape sides) the emulator tries
to determine a name for the saves removing this info, so the savestates
for different sides/disks belong to the same program.
An example of use is when you load a program and then save an state when
you are side2/disk2. Later, in another session, you can directly load
this state without load side1/tape1. Directly insert the medium for
side2/disk2 and load the savestate from menú options or hotkeys combos.
If necessary for tapes you can use the tape browser to position in the
right phase/position to load.
- Show savestate screen as back image in menu
-------------------------------------------
Default enabled.
In the menu for loading and saving states the screen for the savestate
selected is shown as back image.
It can be fully viewed using Right cursor or the 'X' Button.
In the screenshot full view:
- 'A' Button to load the state
- 'B' Button or Left cursor to return to the list of savestates
- Cursor Up and Down to return to the savestates list and select
previous or next savestate.
Options - General GCW0
----------------------
- Triple Buffer
-------------
Default disabled.
Enable/Disable triple buffer.
BUG: Disabling triple buffer sometimes freeze the screen but
emulator will be still running.
If Hotkey combos are enabled you can enable/disable it with the
`L1` + `R1` + `B` combo.
- Adjust screen refresh rate
--------------------------
Default disabled.
Only for OpenDingux firmware based on kernel 5.10 with DRM/KMS
video driver.
If it is enabled the screen refresh rate is changed to the nearest
refresh rate based in the timings and CPU speed for the chosen
machine model.
Use this option with 'Triple Buffer' enabled to synchronize video and
get smooth animations.
See also 'Dynamic sound rate' option.
If Hotkey combos are enabled you can enable/disable it with the
`L1` + `R1` + `A` combo.
Refresh rates:
- 60Hz for Spectrum 48K NTSC and Timex TS2068 models
- 50Hz for all other models
Some visible examples of smooth animatiosns are the scrolling texts
in the main screen of Dan Dare, Commando, Cannibals from Outer Space
or the Savage's intro load.
CPU clock speed for emulated systems are not exactly 50 or 60 Hz.
The sound samples buffer is linked to the emulated CPU clock model
and this cause audio glitches, see 'Dynamic sound rate' option.
- Dynamic sound rate
------------------
Default disabled.
Only for OpenDingux firmware based on kernel 5.10.
Only take efffect with 'Adjust screen refresh rate' enabled.
Every 10 sound frames the rate used in the Blip buffer is adjusted
based on fill level of the sound sfifo buffer. Blip buffer provides
waveform synthesis and sample buffering, the samples it generates are
pushed to sfifo buffer, where soundcard pull them.
This is based on byuu/Near's article "Dynamic Rate Control". This
implementation control sfifo buffer fill level.
See byuu/Near's article on https://byuu.net/audio/dynamic-rate-control/
- Border
------
Default Full.
Use IPU scaling by reducing screen resolution by removing border pixels.
See next opyion to choose your panel type.
The options are:
- Full 320x240. Actual Fuse's full border emulation.
- Large 304x228. Reduce pixels: 16 width, 12 height.
- Medium 228x216. Reduce pixels: 32 width, 24 heigth.
- Small 272x204. Reduce pixels: 48 width, 36 heigth.
- None 256x192. No border. Reduce pixels: 64 width, 48 heigth.
Filters can affect the display depending on panel resolution.
If Hotkey combos are enabled you can switch between Full and None with
`L1` + `R1` + `A` combo.
Operating Systems and scaling with Border option
- RetroFW 1
Scaling do not work.
- RetroFW 2
Scaling works with all filters and spectrum models.
- OpenDingux
* 320x240 panel (GCW0, RG350, RG350P).
Scaling works with all filters and spectrum models.
* 640x480 panel (RG350M)
Scaling works with all filters and spectrum models.
For 1x filters. Large is using 300x225 resolution and Small 272x208.
In mainline beta firmware with 1x filters Small and Large border
don't work and both use Medium border size. With 2x filters they
both border options work work well.
* 480x320 panel (RG280M)
Scaling works with all filters and spectrum models.
For 1x filters. Large is using 304x224 resolution and Small 272x208.
- Panel type
----------
Default 320x240.
Choose your panel type for correct border display with some filters.
This option is only available in OpenDingux legacy, for mainline
OpenDingux (current beta) the panel is auto detected.
- Video filter
------------
Default Bicubic.
Video filter to apply when scaling if border is not full.
- Bicubic sharpness level
-----------------------
Default 2. Minimun 2, maximum value 32.
- Show status bar with border
---------------------------
Default enabled.
Show status bar also when border is not Full.
- Show FSP instead of speed percentage
------------------------------------
Default disbled.
If you want to view FPS instead emulation speed %.
- Filter Known extensions
-----------------------
Default enabled.
Only the supported file extensions will be presented in file
dialogs for save and load operations for known media.
Filter can be enabled/disabled with `Select` button in file
dialogs.
Enable this option can help to avoid overwrite any file type other
than the type pretended to save.
See also 'Confirm overwrite files' option to prevent overwrite
files without advise.
Filters are applied in save dialogs for:
- Save snapshot, Screenshots, Recordings, AY logging, Movie.
- Media types: Tape, Microdrive, Disk (+3, Beta, +D/DISCiPLE,
Didaktik).
- Control mapping files use the '.FCM' extension
(Options -> Joysticks -> Save control mapping to file)
- For profiler saves '.PRF' extension had been chosen in this
port.
No filters are applied for:
- Binary data (File -> Save binary data...)
Filters are applied in load dialogs for:
- Media types: Tape, Disks (+3, Beta, +D/DISCiPLE, Didaktik),
Interface 1, Cartridges.
No filters are applied for:
- Binary data (File -> Load binary data...)
- General open files (File -> Open (or L1 + X hotkey)
Known extesions for media to save:
- Snapshots: .SZX, .Z80 and .SNA
- Tape: .TZX
- Microdrive: .MDR
- +3 Disks: .DSK (only the old CPC format), UDI, FDI
- Beta: .TRD, .SCL, .UDI, .FDI
- Didaktik: .D80, .D40
- Opus: .OPD, .OPU
- +D/Disciple: .IMG, .MGT, .SAD
- Saving screenshots: .SCR, .MLT or .PNG formats.
- In OpenDingux Scalable Vector Graphics: .SVG
- Recordings: .RZX
- Movie files: .FMF
- AY Logging: .PSG
- Control mapping: .FCM
- Profiler: .PRF
If no extension is supplied when enter a name in save dialogs then
the first extension of each media known type will be added to the
name.
- Independent dir access for media type
-------------------------------------
Default disabled.
Each media type dialog will use their own navigation path from the
common inital path.
The common inital path will be:
- If Fuse is loaded selecting a spectrum media file from
GMenu2x/GMenuNx then the loaded program's path..
- If Fuse is loaded withouth file selector:
- The last saved directory if 'Save last directory visited' is
enabled and there is a last directory saved.
- The Fuse's executable path.
- Confirm overwrite files
-----------------------
Default disabled.
Fuse asks for confirmation to overwrite for some media, but not
for all.
This option will ask for confirmation for all overwrites.
It must be convenient to enable it.
- Show hidden files
-----------------
Default disabled.
Show all files and directorys including hidden.
Hidden files begin with .
- Hotkey combos
-------------
Default disabled.
If you want to quick access some functions. See section Hotkey
combinations for details.
- Save last directory visited
---------------------------
Default disabled.
The last visited directory will be saved to use as initial path.
This will be used if Fuse is loaded without file selector.
- GCW0 keyboard: Map LStick to DPad
---------------------------------
Default enabled.
With this option enabled and if GCW0 keyboard mapping is enabled and no
Joystick is mapped then left stick moves are mapped as directional pad
buttons, so they will be use the mapped dpad for GCW0 keyboard.
Options - Media
---------------
- Auto-load media with custom roms:
---------------------------------
Default disabled.
If Machine ROM has been changed the rom files used are not in roms
paths or do not have default names then they will be considered
custom roms and no autoload for media types will be used.
With this option enabled the auto-load will be used despite custom
roms are used.
This will be helpful if different version or language official
ROMS are used and they are not in roms path or not have the
default fuse rom names.
See ROMS section for more details.
------------------------
### Virtual Keyboard ###
------------------------
Press the `Start` button to open a Virtual Keyboard when you are in
emulator.
The keys in keyboard correspond to ZX Spectrum 48k keys.
When you press them are send to emulator as if you are using a real
ZX Spectrum keyboard.
`Cursor` Move to select keys.
`A` Press selected key.
`B` Lock key. It's marked in blue.
The locked keys are used when press the `A` button over
a Key and then are unlocked.
For use in combinations of Caps Shift or Symbol Shift
with other keys.
For example: In 48k mode you can Lock key "Ss" and then
press 'Cs' key to change keyboard to "Extended" mode.
`X` Sticky key. It's marked in Red.
The key is continously pressed.
For example: In 48k mode you can press key 'J' then
Sticky key 'Ss' and then press twice key 'P' to obtain
'LOAD ""'.
`Y` Clean all Lock and Sticky keys.
`Start` Close Virtual Keyboard
`L1`, `R1` Change the Virtual Keyboard position.
There are 4 positions, one for earch corner of screen.
-------------------------------------
### Buttons in different contexts ###
-------------------------------------
=>Some machines don't have Sticks or `L2`, `R2` buttons.
Buttons in emulator:
--------------------
The buttons function detailed are when no mapping is assigned.
`Cursor` Shifted cursor ZX Spectrum keys (5, 6, 7 and 8 keys)
This is modified with "Use shift with arrow keys" option
`A`, `B` Symbol Shift
`Y` CAPS Shift
`X` Space

If hotkey combos enabled: Start a hotkey combo
`Left Stick`
Nothing.
On some systems you can map it as cursor
`Right Stick`
Nothing.
On some systems you can enable an emulated mouse that
uses the right stick to move the mouse
In Fuse you can use it as Kempston mouse
|In RG350 you can enable it with `Power`+`B` hotkey
`L2` Nothing.
Left click with mouse emulation enabled
`R2` Nothing.
Right click with mouse emulation enabled
Buttons in Menu:
----------------
These are no dependent of button mapping.
`Cursor`, `Left Stick`
Move
`A` Select the option or accept the options at form
`B` Cancel and go back to previous menu or to the emulator
if there is no previous menu
`X` At different contexts:
- Mark/Unmark for check options.
Example: General options -> Auto-save settings
- Open list of options for list options.
Example: Sound options -> AY stereo separation
- It open 'enter name' dialog for file save dialogs.
`Y` At save dialogs save with the default name and type.
Default name will be the name of the last loaded file
name with its extension changed to default extension of
media to save.
In Poke memory is used to add a new poke.
`Select` Enable/Disable filters in file dialogs if option
`Filter known extensions` option is enabled.
Cancel and exit completely from any level of menu to the
emulator
`L1` Go to the first menu option
`R1` Go to the last menu option

directory
`R2` In file selector go to the last entry in the current
directory
`Start`, `L2`, `R3`, `Right Stick`
Nothing
#### Maintain options ####
--------------------------
Some menu options open a form with options to check/uncheck or choose
an option from a list.
- To check/uncheck options use `X` button.
- To confirm changes in form use the `A` button.
- To cancel changes in form use the `B` or `Power` buttons.
Some examples of forms are General, Media and Sound.
#### Virtual keyboard in menu options ####
------------------------------------------
In some menu options the virtual keyboard is presented to allow to use
different options presented or enter values.
Examples where the virtual keyboard it's appearing are: 'Enter name'
for save dialogs, Debugger, Poke Finder, Poke Memory.
`Cursor` Move to select keys
`A` Press the selected key
`X` Change the keyboard mode between upper and lower case and
some additional characters
`Y` Delete previous character
`B` Cancel and exit to previous option in menu
Confirm input
To confirm the input press 'En' key at virtual Keyboard
|For the 'Enter the name' in save dialogs the last loaded filename
without the extension is proposed.
------------------------------------------------
### Mapping buttons to Joysticks or Keyboard ###
------------------------------------------------
You can map handheld buttons to Joysticks or Spectrum keys in
`Menu -> Options -> Joysticks`
==== GCW0 Joystick 1 ====
This option allows to emulate a ZX Spectrum joystick with the handheld
buttons. It also allows you to assign keyboard keys to buttons
- Type: Choose the Joystick to emulate or None. Default is None.
- Button mapping: Map the handheld buttons to Joystick fire,
ZX Spectrum keys or to Nothing.
Some type of Joysticks may require other emulator options enabled.
|For example for Kempston joystick emulation need enabled
|'Kempston joystick' in `Menu -> Options -> Peripherals -> General`.
By default all buttons are mapped to Joystick fire.
==== GCW0 Keyboard ====
This option allows to map handheld buttons to ZX Spectrum keys.
The cursors also can be mapped.
- Type: Choose Activated or None. Default is None.
- Button mapping: Map buttons to ZX Spectrum keys or Nothing.
By default all buttons are mapped to Nothing.
--------------------------
When both mappings, "GCW0 Joystick 1" and "GCW0 Keyboard", are enabled
at the same time only "GCW0 Joystick 1" will work.
When you choose any 'Type' other than "None" in "GCW0 Joystick 1" or
"GCW0 Keyboard", some buttons may lose their original functionality if
they are mapped to joystick fire or to keyboard keys:
- `Select`, `Start`, `L1` and `R1` buttons have functionanility
that may be lost.
- If you have mapped the `Select` button, you can still access the
menu with the` Power` button.
----------------------------------------------
### Control mapping per game configuration ###
----------------------------------------------
To have control gaming configuration per game you must activate it in
the menu 'Options -> Joysticks -> Control mapping'.
Files for save control mapping:
- The configuration files per game are saved in 'mappings' directory
in fuse config path ($HOME/.fuse/mappings).
- They have extension '.fcm' (fcm is for Fuse Control Mapping).
- The options saved are the 'Types' and buttons mappings for
GCW0 Joystick 1, Joystick 2, Keyboard and GCW0 Keyboard.
- The format of the file is the same used for the general settings:
XML for OpenDingux or plain text for RetroFW.
- By default for the control mapping filenames will be tried to
detect some patterns on name to cut them off:
- All the denominations between '()' or '[]'
- 'Tape', 'Disk', 'Side' for 'ABCD' or '1234', 'Part 1234 of 1234'
- The '128k', '48k' out of '()' '[]'
- The 'Small, Medium, Large' whatever 'Case'
(The search of patterns are case insensitive)
The supported media for auto-load control mapping files are tapes,
microdrives, snapshots, disks (not IDE), rom cartridges and
Timex cartridges.
See PITFALLs at the end of this section.
Options:
- Control mapping per game:
-------------------------
Default disabled.
Enable the save and load of control mappings per game for
supported media: tapes, snapshots, disks (not IDE),
rom cartridges, Timex cartridges.
If you disable it:
- If defaults are detached they are saved and restored as
current defaults.
- If changes were made to controls those changes are saved to
correponding control mapping file.
If you enable it:
- If defaults are detached they are loaded.
- If you do after you have load any supported media the emulator
try to initialize control mapping for that media.
- Auto-load:
----------
Default enabled.
Only take effect if 'Control mapping per game' is enabled.
If enabled the autoload of control mapping files associated to the
file loaded.
This apply for supported media when are loaded from 'File -> Open'
or inserted from the 'Media' menu.
- Auto-save:
----------
Default enabled.
Only take effect if 'Control mapping per game' is enabled.
If controls mapping has changed then the autosave will be at this
events:
- Load another media
- Clear or eject the media in the file at 'Media' menu
- Disabling 'Control mapping per game'
- Exit the emulator
- Not detached defaults:
----------------------
Default disabled.
Only take effect if 'Control mapping per game' is enabled.
If this option is enabled you can't maintain separated default
controls.
The default controls are used:
- At start of Fuse, if no media is autoload or no control
mapping autoload is enable
- When you insert a media with not yet control mapping
configuration
- When you clear or eject a media
- No cut/transform filenames:
---------------------------
Default disabled.
Only take effect if 'Control mapping per game' is enabled.
With this option enabled the filename for mapping control will be
the same of the file loaded replacing the extension by '.fmc'.
With this option disabled the control mapping filename follow the
rules indicated above.
- Enable Kempston Joystick if needed:
-----------------------------------
Default enabled.
Only take effect if 'Control mapping per game' is enabled.
If control mapping to load have assigned Kempston Joystick in
GCW0 Joystick 1, Joystick 2 or Keyboard and 'Kempston Joystick'
option is not enabled in Peripherals -> General then it will be
enabled.
When load a program if the control mapping file not exist yet but
default controls have assigned Kempston Joystick in GCW0
Joystick 1, Joystick 2 or Keyboard then the same logic is applied.
NOTE: Custom control mapping is not intended to manage hardware
attached to machine, only control mappings.
But enabling/disabling Kempston Joystick without reset machine is
supported by Fuse.
Other peripherlas as Fuller Box need to reset the machine and this
is not viable to manage in control mapping.
When you exit from Fuse and have General Auto-save setting enabled
then default control mapping will be saved at general file.
Other options in Joystick menu for Control mapping:
- Load control mapping:
---------------------
Enabled if 'Control mapping per game' is enabled.
When a control mapping file exists for the last media loaded then
it's name will be printed here, only the first 20 characters of
name.
This option allows to restore controls mapping from configuration
file if changes have been made to them.
- Save control mapping:
---------------------
Enabled if 'Control mapping per game' is enabled.
If supported media is inserted then the name of control mapping
file will be printed here, only the first 20 characters of name.
This allow you to save the current control mapping if changes have
been made to them or if the file does not exist yet.
If Auto-save of control mapping is active the save will be at
designed events, see 'Auto-save' options. You can force the save
with this option.
- Load control mapping from file:
-------------------------------
Allways enabled.
This option allow you to load a control mapping file to change the
current control mappings.
- Save control mapping from file:
-------------------------------
Allways enabled.
This option allows you to save a control mapping file with the
current control mappings.
- Default control mapping:
------------------------
Enabled when 'Control mapping per game' is enabled and
'Not detached defaults' is disabled.
Submenu to maintain default control mapping.
- Reset to default controls:
--------------------------
Enabled when 'Control mapping per game' is enabled and
'Not detached defaults' is disabled.
Reset the current controls to default control mapping.
- Set current as default:
-----------------------
Enabled when 'Control mapping per game' is enabled and
'Not detached defaults' is disabled.
Set the current controls as the default control mapping.
PITFALLS:
Variants of the same program:
If 'No cut/transform filenames' is disabled (default) the emulator
try to clean the name of filename to make it equal name for
variations.
But if the filenames used are no consistent, including letter
case, then a different name for the same program may be determined.
When insert various media the last inserted will be the selected
control mapping.
- If you unload it then it will be cleared and you could start a
game from other media inserted with no file control mapping.
- If you start from Loader the system can load from media
different to the last assigned control mapping file.
Example:
1.- Select +3 machine
2.- Open media menu and insert a disk
3.- Open media menu and insert a tape
4.- The control mapping file will be the last tape inserted
5.- Open media menu and clear tape
6.- Now there is not control mapping file assigned but you can
load a program from disk
Bugs aside, probably there are other scenarios not taken into
account but I believe that the most relevant use cases are covered.
-------------------------
### External joystick ###
-------------------------
On some handhelds it is possible to connect an external Joystick using
USB OTG. The mapping of 'Joystick 2' will be applied to it.
For controllers the number of each button in mapping depends on the
controller layout.
=>Fuse count buttons from 1 not from 0, so add 1 to translate your
layout into Fuse's config.
|On my RG350 I've tested this with an 8Bitdo FC30 Pro controller.
|The mapping layout:
|A=1, B=2, X=4, Y=5, L1=7, R1=8, L2=9, R2=10, Select=11, Start=12,
|L3=14, R3=15.

-------------------------
### External keyboard ###
-------------------------
I don't have tested a Keyboard on USB OTG but in theory it should work.
But keep in mind that current adaptations made for handhelds buttons
have probably made it unusable.
The handheld buttons are keystrokes that have conflict with some keys
used for SDL menus.
----------------------
### Kempston mouse ###
----------------------
In some handhelds you can emulate mouse with the Right stick and
`L2`, `R2` buttons.
This make possible emulating the Kempston mouse.
You must enable 'Kempston mouse' in the peripherals:
`Menu -> Options -> Peripherals -> General`, and enable the mouse
emulation in the handheld.
|In the RG350 you can activate the mouse with hotkey `Power` + `B`.
---------------------
### Triple Buffer ###
---------------------
There is an implementation to use the triple buffer. It can be enabled
at 'General GCW0' options or whith combo hotkeys 'L1' + 'R1' + 'B'.
If tripple buffer is activated then an [B] will be at status line.
It affects to the speed of emulator that can be observed in the speed
for fastloading.
In general I believe that is not needed, but I've seen diference
activating it on some demos for Pentagon's models as "mescaline
synesthesia by deMarche".
BUG: At disabling triple buffer sometimes the screen will be frozen
but the emulator still will be running .
This is surely motivated by some mistake on my code or for
missunderestanding triple buffer by my side.
---------------------------
### Hotkey combinations ###
---------------------------
For use hotkey combos they must be enabled in
'Menu -> Options -> General GCW0'.
If `L1` and `R1` buttons are not mapped to Joystick or Keyboard it
will be used to start the hotkey combinations.
The implemented hotkeys correspond to Fx key functions in Fuse's SDL
implementation:
L1 + R1 + A Switch between Full and None border
L1 + R1 + B Toggle triple buffer
L1 + R1 + X JoystickS
L1 + Select + Y Tape play (F8)
L1 + A Tape open (F7)
L1 + B Save file (F2)
L1 + X Open file (F3)
L1 + Y Media menu
R1 + A General options (F4)
R1 + B Reset machine (F5)
R1 + X Exit fuse (F10)
R1 + Y Machine select (F9)
L1 + Cursor down Quicksave state for current slot
R1 + Cursor Up Quickload state for current slot
R1 + Cursor right Increase slot to use
R1 + Cursor left Decrease slot to use
---------------------
### Media options ###
---------------------
If you have problems loading some programs keep in mind the
compatibility issues of software with the model emulated.
Also some options in 'Media' options can influence to some loaders as
'Accelerate loaders'. Try enabling/disabling different otions.
------------
### ROMs ###
------------
Fuse provides roms for some systems and peripherals it emulate but not
for all models or peripherals that it support.
You can assign new roms or change the defaults from the emulator
itself:
- Open menu with `Select` or `Power` button.
- Then navigate from Menu --> Options -> Select Roms -> Machine ROMs
or Peripheral ROMs
- With `cursor` select the rom to change and press `X` button
- At file selector use the `cursor` keys to navigate to folder where
your roms are located and to select the needed rom. And press the
`A` button to confirm selection.
- Repeat until all the needed ROMs are assigned.
- Finally do accept all pressing the `A` button.
You can reset a rom to default with the `Y` button.
NOTE:
The emulator detect your rom as custom if they not have the name
expected, including the path.
This affect to auto-load media (tapes, disks). In standard Fuse
compilation cutoms roms don't autoload.
The option "Auto-load media with custom rom" in General options
(default False) auto-load also with custom roms.
Also roms con be added to the 'rom' directory in Fuse config path.
Fuse search in this path for rom files with the default names.
Fuse config path is located in "$HOME/.fuse/roms":
For OpenDingux "/media/data/local/home/.fuse/roms"
For RetroFW "/home/retrofw/.fuse/roms"
|Fuse will create the config paths at starting if they don't exist.

NAME
fuse -- Sinclair ZX Spectrum emulator
SYNOPSIS
fuse [options]
DESCRIPTION
Fuse is a Sinclair ZX Spectrum emulator. It supports several models
(including the 128), with quite faithful emulation of the display and
sound.
The emulator can load any of the formats supported by libspectrum(3) --
this includes Z80, SNA and SZX snapshots, and PZX, TAP and TZX virtual-
tape files. Saving to SZX, Z80 and SNA snapshots and TZX and TAP tape
files is supported. The SLT extension to the Z80 format is partly sup-
ported (enough for multi-load games); however, loading of the old DAT-
file variant is not.
DSK, UDI, FDI, TD0, MGT, IMG, D40, D80, SAD, TRD, SCL and OPD disk im-
ages are supported when a disk interface is being emulated, including
the integrated disk drives on +3, Pentagon or Scorpion machines as well
as the +D, DISCiPLE, Opus Discovery, Beta 128 and Didaktik 80 inter-
faces. DCK cartridge images are supported when emulating a Timex 2068
variant. Interface 2 ROM cartridges are also supported.
Finally, there is also support for reading and writing the RZX input
recording format.
See the COMPRESSED FILES section for details on reading files com-
pressed with bzip2(3), gzip(3) or zip(3).
OPTIONS
--accelerate-loader
Specify whether Fuse should attempt to accelerate tape loaders
by "short circuiting" the loading loop. This will in general
speed up loading, but may cause some loaders to fail. (Enabled
by default, but you can use `--no-accelerate-loader' to dis-
able). The same as the Media Options dialog's Accelerate loaders
option.
--aspect-hint
Specify whether the GTK and Xlib user interfaces should `hint'
to the window manager about the preferred aspect ratio for the
graphics window, thus preventing resizing to non-square sizes
which lead to Fuse not displaying correctly. This option has
been observed to cause problems with some window managers when
using the GTK UI which can prevent the window from being resized
or moved at all. (Enabled by default, but you can use `--no-as-
pect-hint' to disable). See also the `--strict-aspect-hint' op-
tion.
--autosave-settings
Specify whether Fuse's current settings should be automatically
saved on exit. The same as the General Options dialog's Auto-
save settings option.
--auto-load
Specify whether tape and disk files should be automatically
loaded when they are opened using the File, Open... menu op-
tion. In the case of TRD/SCL disk images, inserts also a boot
loader file when none is available. (Enabled by default, but you
can use `--no-auto-load' to disable). Same as the Media Options
dialog's Auto-load media option.
--beta128
Emulate a Beta 128 interface. Same as the Disk Peripherals Op-
tions dialog's Beta 128 interface option.
--beta128-48boot
When a Beta 128 interface is used in 48K or TC2048 emulation the
option additionally controls whether the machine boots directly
into the TR-DOS system. Same as the Disk Peripherals Options di-
alog's Beta 128 auto-boot in 48K machines option.
--betadisk file
Insert the specified file into the emulated Beta disk inter-
face's drive A: and select Pentagon mode on startup.
--bw-tv
Specify whether the display should simulate a colour or black
and white television. This option is effective under the GTK,
Win32, Xlib and SDL user interfaces: the others will always sim-
ulate a colour TV. The same as the General Options dialog's
Black and white TV option.
--cmos-z80
This option specifies that Fuse should emulate a CMOS Z80, as
opposed to an NMOS Z80. Same as the General Options dialog's Z80
is CMOS option.
--competition-code code
Specify the code to be written to competition mode RZX files.
The same as the RZX Options dialog's Competition code option.
--competition-mode
Specify whether input recordings should be made in `competition
mode'. The same as the RZX Options dialog's Competition mode
option.
--compress-rzx
Specify whether RZX files should be written out compressed. (En-
abled by default, but you can use `--no-compress-rzx' to dis-
able). Same as the RZX Options dialog's Compress RZX data op-
tion.
--confirm-actions
Specify whether `dangerous' actions (those which could cause
data loss, for example resetting the Spectrum) require confirma-
tion before occurring. (Enabled by default, but you can use
`--no-confirm-actions' to disable). This option is the same as
the General Options dialog's Confirm actions option.
--covox
Emulate a Covox sound interface for Pentagon/Scorpion. Same as
the General Peripherals Options dialog's Covox option.
--debugger-command string
Specify a debugger command to be run before emulator startup.
This can be used to set breakpoints or the like. Currently, this
is the only method to input multi-line debugger commands. (See
the MONITOR/DEBUGGER section for more information).
--detect-loader
Specify whether Fuse should attempt to detect when the tape is
being accessed and start and stop the virtual tape playing auto-
matically. (Enabled by default, but you can use `--no-de-
tect-loader' to disable). Same as the Media Options dialog's De-
tect loaders option.
--disciple
Emulate a DISCiPLE interface. Same as the Disk Peripherals Op-
tions dialog's DISCiPLE interface option.
--discipledisk file
Insert the specified file into the emulated DISCiPLE's drive 1.
--didaktik80
Emulate a Didaktik 80 (or Didaktik 40) disk interface. Same as
the Disk Peripherals Options dialog's Didaktik 80 interface op-
tion.
--didaktik80disk file
Insert the specified file into the emulated Didaktik 80 (or Di-
daktik 40)'s drive A.
--disk-ask-merge
Prompt the user to confirm whether Fuse should try to merge the
`B' side of a disk image from a separate file when opening a new
single-sided disk image.
--disk-try-merge mode
Select whether Fuse should try to merge a separate file for the
`B' side of a disk image separate file when opening a new disk
image. Most double sided disk images are dumped as two single
sided disk images e.g. `Golden Axe - Side A.dsk' and `Golden
Axe - Side B.dsk'. So, if we want to play Golden Axe, first we
have to insert the first disk image and when the game asks to
insert side B, we have to find and open the second disk image,
instead of just `flip'-ing the disk inside the drive. If en-
abled, Fuse will try to open the second image too and create a
double sided disk image (merging the two one sided disk images)
and insert this merged virtual disk into the disk drive. The
function detects whether the file is one side of a double-sided
image if the filename matches a pattern like [Ss]ide[
_][abAB12][ _.] in the file name of a disk that is being opened.
If found, Fuse will try to open the other side of the disk too
substituting the appropriate characters in the filename e.g.
1->2, a->b, A->B. If successful then it will merge the two im-
ages and now we have a double sided disk in drive. This means
that if we open `Golden Axe - Side A.dsk', then Fuse will try to
open `Golden Axe - Side B.dsk' too. Now, we can just `flip' the
disk if Golden Axe asks for `Side B'. The available options are
Never, With single-sided drives and Always.
--divide
Emulate the DivIDE interface. The same as the Disk Peripherals
Options dialog's DivIDE interface option.
--divide-masterfile file
--divide-slavefile file
Specify an IDE image to be loaded into the DivIDE's emulated
master and slave drives respectively.
--divide-write-protect
Specify that the emulated DivIDE's write protect jumper should
be considered set. The same as the Disk Peripherals Options dia-
log's DivIDE write protect option.
--divmmc
Emulate the DivMMC interface. The same as the Disk Peripherals
Options dialog's DivMMC interface option.
--divmmc-file file
Specify an HDF image to be loaded into the DivMMC's emulated
memory card.
--divmmc-write-protect
Specify that the emulated DivMMC's write protect jumper that
protects EEPROM should be considered set. The same as the Disk
Peripherals Options dialog's DivMMC write protect option.
--dock file
Insert the specified file into the emulated Timex 2068 variant
dock; also select the TC2068 on startup if available.
-D mode
--doublescan-mode mode
Specify whether to use doublescan modes in the FB UI. Available
values for mode are 0, 1 and 2. 0 means `never doublescan' (use
640x480 at either 72 Hz or 60 Hz), whereas 1 and 2 both mean
`try to use doublescan' and will fall back on the 640x480 modes.
1 selects 72 Hz modes (the same size and shape as your typical
640x480), and 2 selects 60 Hz modes (overscan).
If your monitor displays a blank screen when using 1 or 2, press
F10 then try a different option or say `--fbmode 640'.

TC2048, 128K or +2 (trdos.rom), the +D ROM (plusd.rom), the Di-
daktik 80 ROM (didaktik80.rom), the DISCiPLE ROM (disciple.rom),
the Multiface One ROM (mf1.rom), the Multiface 128 ROM
(mf128.rom), the Multiface 3 ROM (mf3.rom), the Opus Discovery
ROM (opus.rom), the SpeccyBoot ROM (speccyboot-1.4.rom), the
TTX2000S ROM (ttx2000s.rom), and the Source ROM (usource.rom).
The names in brackets denote the defaults. Note that not all
these ROMs are supplied with Fuse -- you must supply your own
copies of those which are not.
--no-rs232-handshake
This option makes Fuse's Interface 1 emulation assume that the
RS-232 line other end is live when you connect the communication
channels. See also the `--rs232-rx' and `--rs232-tx' options.
--rs232-rx
--rs232-tx
Specify the communication channels (FIFO or file) to be used for
Interface 1 RS-232 emulation as RxD and TxD wire. See also the
`--rs232-handshake' options.
--rzx-autosaves
Specify that, while recording an RZX file, Fuse should automati-
cally add a snapshot to the recording stream every 5 seconds.
(Default to on, but you can use `--no-rzx-autosaves' to dis-
able). Same as the RZX Options dialog's Create autosaves option;
see there for more details.
--sdl-fullscreen-mode mode
Select a screen resolution for full screen mode. Available val-
ues for mode are listed in a table, when Fuse is called with
--sdl-fullscreen-mode list command line option. This option is
effective only under the SDL UI.
--separation type
Give stereo separation of the 128's AY sound channels. Same as
the General Options dialog's AY stereo separation option. The
available options are None, ACB, and ABC. The default option is
None.
--simpleide
Specify whether Fuse will emulate the simple 8-bit IDE interface
as used by the Spectrum +3e. Same as the Disk Peripherals Op-
tions dialog's Simple 8-bit IDE option.
--simpleide-masterfile file
Specify a HDF file to connect to the emulated Simple 8-bit IDE
interface's master channel.
--simpleide-slavefile file
Specify a HDF file to connect to the emulated Simple 8-bit IDE
interface's slave channel.
--slt
Support the SLT trap instruction. (Enabled by default, but you
can use `--no-slt' to disable). Same as the Media Options dia-
log's Use .slt traps option.
-s file
--snapshot file
Specify a snapshot file to load. The file can be in any snapshot
format supported by libspectrum(3).
--sound
Specify whether Fuse should produce sound. (Enabled by default,
but you can use `--no-sound' to disable). Same as the Sound Op-
tions dialog's Sound enabled option.
-d device
--sound-device device
Specify the sound output device to use and any options to give
that device. If you are not using the SDL UI or using libao or
libasound (ALSA) for sound output, then the device parameter
just specifies the device to be used for sound output.
If you are using the SDL UI, the device parameter allows you to
specify the audio driver to be used (e.g. dsp, alsa, dma, esd
and arts).
If you are using libao for sound output, the device parameter
allows you to specify the device used for sound output (either
`live' to a speaker or to a file) and the parameters to be used
for that device. In general, the device parameter has the form
driver[:param[=value][,param[=value][,...]]. driver selects the
libao driver to be used, either one of the `live' drivers (aixs,
alsa, alsa09, arts, esd, irix, macosx, nas, oss or sun) or a
file driver (au, raw, wav or null). The available parameter and
value pairs for each device are:
o aixs: AIX audio system
o dev=device
`device' gives the AIX sound device.
o alsa: Advanced Linux Sound Architecture version 0.5.x
o card=num
`num' gives the ALSA card number.
o dev=num
`num' gives the ALSA device number.
o buf_size=num
`num' gives the ALSA buffer size in bytes.
o alsa09: Advanced Linux Sound Architecture version 0.9+
o dev=string
`string' specifies the ALSA device e.g. hw:1.2
o buffer_time=num
`num' gives the ALSA buffer time in microseconds.
o period_time=num
`num' gives the ALSA period time in microseconds.
o use_mmap=yes|y|true|t|1
specifies that libao use memory mapped transfer.
o arts: aRts soundserver: no parameters.
o esd: Enlightened Sound Daemon.
o host=string
`string' gives the ESD host specification.
o irix: IRIX Audio Library: no parameters.
o macosx: MacOS X CoreAudio: no parameters.
o nas: Network Audio System.
o host=string
`string' gives the NAS host specification.
o buf_size=num
`num' gives the buffer size on the server.
o oss: Open Sound System.
o dsp=string
`string' gives the OSS device to be used e.g.
/dev/sound/dsp1
o sun: SUN audio system.
o dev=string
`string' gives the audio device to be used.
o au: SUN Sparc audio file: no parameters.
o raw: raw file.
o byteorder=string
`string' can be any of native (host native byte-
order), big (big endian) or little (little en-
dian).
o wav: Microsoft audio file: no parameters.
o null: null output: no parameters.
o debug: for debugging libao.
Finally, each of the file output types (au, raw and wav) have an
extra option `file=filename' where `filename' gives the file
output will be directed to. This defaults to `fuse-sound.ao' if
it is not specified.
Some examples of use:
fuse -d alsa09:dev=hw:1
causes Fuse to use ALSA 0.9+ output with the second (#1) sound
card.
fuse -d raw:byteorder=little,file=enigma.raw
causes Fuse to save little endian words to `enigma.raw'.
See the `DEVICE' section of ogg123(1) for up to date information
of devices and options (except for the `file' option which is
provided by Fuse itself).
If you are using libasound or ALSA for sound output, the device
parameter allows you to specify the device used for sound output
and some parameters to be used for that device. In general, the
device parameter has the form
devstr or
param[=value][,param[=value][,...][,devstr].
o devstr: selects the ALSA device used, it can be any com-
plex or simple ALSA device name. e.g.: default or hw:0 or
tee:plughw:0,'/tmp/out.raw',raw. See the alsa-lib pcm
api reference at
http://www.alsa-project.org/alsa-doc/alsa-lib/pcm.html
for further explanation.
o param and values:
o buffer=nnnn: set the ALSA buffer in frames,
smaller value cause smaller sound delay but may
more buffer underrun (pops and clicks), larger
value cause longer delay but fewer underrun. By
default Fuse determine the buffer size based on
the actual sound frequency.
If you use some special plugin for your pcm device
(e.g.: dmix) or your card not support some needed
parameter (e.g. cannot play other only 48 kHz
stereo sound like some AC97 sound card) may cause
Fuse unable to set the needed buffer size, appro-
priate sound frequency, channels and so on, there-
fore you cannot get optimal result or not hear the
sound at all. In this case try the plughw:#,
(where # mean your card number counted from 0) for
ALSA device.
o verbose : if given, fuse report ALSA buffer under-
runs to stderr.
Some examples of use:
fuse -d verbose,buffer=2000
causes Fuse to use the default ALSA device with 2000 frame
length buffer and report ALSA buffer underruns on stderr.
fuse -d tee:plughw:0,'/tmp/aufwm.raw',raw
causes Fuse to use the first card and parallel save the raw au-
dio samples into /tmp/aufwm.raw file.
If you are using PulseAudio for sound output, the device parame-
ter allows you to specify some parameters to be used for that
soud buffer. In general, the device parameter has the form
param[=value][,param[=value][,...].
o param and values:
o tlength=[num]ms: set target length of the PulseAu-
dio sound buffer in milliseconds. Smaller value
cause smaller sound delay but more buffer under-
runs (pops and clicks), larger value cause longer
delay but fewer underruns. By default Fuse set the
buffer size to 30ms of sound delay.
o tlength=num: set target length of the PulseAudio
sound buffer in bytes. By default Fuse set the
buffer size to 30ms of sound delay.
o verbose : if given, Fuse report PulseAudio buffer
underruns to stderr and PulseAudio buffer options
to stdout.
Some examples of use:
fuse -d tlength=40ms
causes Fuse to target 40ms of sound delay instead of the default
30ms.
fuse -d verbose,tlength=2646
causes Fuse to request a sound buffer of 2646 bytes and print
info to stdout.
--sound-force-8bit
Force the use of 8-bit sound, even if 16-bit is possible. Same
as the Sound Options dialog's Force 8-bit option.
-f frequency
--sound-freq frequency
Specify what frequency Fuse should use for the sound device, the
default is 44.1 kHz, but some devices only support a single fre-
quency or a limited range (e.g. 48 kHz or up to 22 kHz).
--speaker-type type
Select the output speaker emulation, type can be TV speaker,
Beeper or Unfiltered. Same as the Sound Options dialog's Speaker
type option.
--speccyboot
Emulate a SpeccyBoot Ethernet interface. Same as the General Pe-
ripherals Options dialog's SpeccyBoot option. See the SpeccyBoot
web page at http://patrikpersson.github.io/speccyboot/ for full
details on the SpeccyBoot.
--speccyboot-tap device
Specify the TAP device to use for SpeccyBoot emulation.
--specdrum
Emulate a SpecDrum interface. Same as the General Peripherals
Options dialog's SpecDrum option. See the World of Spectrum In-
foseek web page at http://www.worldofspectrum.org/infos-
eekid.cgi?id=1000062 for manuals, software and more.
--spectranet
Specify whether Fuse will emulate the Spectranet Ethernet inter-
face. Same as the General Peripherals Options dialog's Spec-
tranet option. See the SPECTRANET EMULATION section for more de-
tails.
--spectranet-disable
This option controls the state of the Spectranet automatic page-
in jumper (J2). Same as the General Peripherals Options dialog's
Spectranet disable option. See the SPECTRANET EMULATION section
for more details.
--speed percentage
Specify the speed (as a percentage of real Spectrum speed) at
which emulation should attempt to proceed. Same as the General
Options dialog's Emulation speed option.
--statusbar
For the GTK and Win32 UI, enables the statusbar beneath the dis-
play. For the Xlib and SDL UI, enables the status icons showing
whether the disk and tape are being accessed. Same as the Gen-
eral Options dialog's Show statusbar option.
--strict-aspect-hint
For the GTK UI, use stricter limits for the aspect ratio limits
set by the `--aspect-hint' option. This can cause some window
managers (for example, metacity(1)) to not allow the window to
be resized and moved, but is necessary to prevent others (for
example, fvwm(1)) from being able resize the window away from
square.
-t file
--tape file
Specify a virtual tape file to use. It must be in PZX, TAP or
TZX format.
--teletext-addr-1 address
--teletext-addr-2 address
--teletext-addr-3 address

Specify address or hostname of teletext packet servers.
--teletext-port-1 port
--teletext-port-2 port
--teletext-port-3 port
--teletext-port-4 port
Specify TCP port of teletext packet servers.
--textfile file
Set the filename used for text output from the emulated print-
ers. See the PRINTER EMULATION section below for more details.
--traps
Support traps for ROM tape loading/saving. (Enabled by default,
but you can use `--no-traps' to disable). Same as the Media Op-
tions dialog's Use tape traps option.
--ttx2000s
Emulate a TTX2000S teletext adaptor. Same as the General Periph-
erals Options dialog's TTX2000S option. See the TTX2000S EMULA-
TION section for more details.
--unittests
This option runs a testing framework that automatically checks
portions of code, comparing actual results with expected ones.
It is meant to detect broken code before a release. There is not
graphical mode, the program just ends with exit code 0 if all
tests are good or prints error messages to stdout and ends with
exit code greater than 0 if there are failed tests.
--usource
Emulate a Source interface. Same as the General Peripherals Op-
tions dialog's Source option.
-V
--version
Show which version of Fuse is being used.
--volume-ay volume
Sets the relative volume of the AY-3-8912 chip from a range of
0-100%. Same as the Sound Options dialog's AY volume option.

Disk Peripherals Options dialog's ZXATASP interface option.
--zxatasp-upload
Specify the state of the ZXATASP upload jumper. Same as the Disk
Peripherals Options dialog's ZXATASP upload option.
--zxatasp-write-protect
Specify the state of the ZXATASP write protect jumper. Same as
the Disk Peripherals Options dialog's ZXATASP write protect op-
tion.
--zxatasp-masterfile file
Specify a HDF file to connect to the emulated ZXATASP inter-
face's master channel.
--zxatasp-slavefile file
Specify a HDF file to connect to the emulated ZXATASP inter-
face's slave channel.
--zxcf
Specify whether Fuse emulate the ZXCF interface. Same as the
Disk Peripherals Options dialog's ZXCF interface option.
--zxcf-upload
Specify the state of the ZXCF upload jumper. Same as the Disk
Peripherals Options dialog's ZXCF upload option.
--zxcf-cffile file
Specify a HDF file to connect to the emulated ZXCF interface.
--zxmmc
Emulate the ZXMMC interface. The same as the Disk Peripherals
Options dialog's ZXMMC interface option.
--zxmmc-file file
Specify an HDF image to be loaded into the ZXMMC's emulated mem-
ory card.

Emulate the ZX Printer. Same as the General Peripherals Options
dialog's ZX Printer option.
All long options which control on/off settings can be disabled using
`--no-foo' (for an option `--foo'). For example, the opposite of
`--issue2' is `--no-issue2'. These options can also be modified while
the emulator is running, using the options dialogs -- see the documen-
tation for the Options menu in the MENUS AND KEYS section for details.
THE VARIOUS FRONT-ENDS
Fuse supports various front-ends, or UIs (user interfaces). The usual
one is GTK-based, but there are also SDL, Win32, Xlib and framebuffer
ones.
The important difference to note is that GTK and Win32 versions uses
`native' dialog boxes etc. (behaving like a fairly normal GUI-based
program) while the others use an alternative, Fuse-specific `widget
UI'. This latter front-end is easily spotted by the way it uses the
main Fuse window/screen for menus and dialogs, and uses the Spectrum's
own font.
MENUS AND KEYS
Since many of the keys available are devoted to emulation of the Spec-
trum's keyboard, the primary way of controlling Fuse itself (rather
than the emulated machine) is via the menus. There are also function
key shortcuts for some menu options.
In the GTK and Win32 version, the menu bar is always visible at the top
of the Fuse window. You can click on a menu name to pop it up. Alterna-
tively, you can press F1 to display a pop-up version of the menu bar,
which you can then navigate with the cursor keys or mouse.
In the widget UI pressing F1 is the only way to get the main menu; and
unlike the GTK version, the emulator pauses while the menus are being
navigated. The menus show which key to press for each menu option in
brackets. Pressing Esc exits a menu, and pressing Enter exits the menu
system entirely (as well as `confirming' any current dialog).
Here's what the menu options do, along with the function key mappings
for those items which have them:
F3
File, Open...
Open a Spectrum file. Snapshots will be loaded into memory; tape
images will be inserted into the emulated tape deck, and if the
Auto-load media option is set will being loading. Opening a disk
image or a Timex dock image will cause the appropriate machine
type (+3, Pentagon or TC2068) to be selected with the image in-
serted, and disks will automatically load if the Auto-load media
option is set. See the FILE SELECTION section below for details
on how to choose the file. Note that this behaviour is different
from previous versions of Fuse, when this option would open only
snapshots.
F2
File, Save Snapshot...
Save a snapshot (machine state, memory contents, etc.) to file.
You can select the filename to be saved to. If it has a .szx,
.z80 or .sna extension, the snapshot will be saved in that for-
mat. Otherwise, it will be saved as a .szx file.
File, Recording, Record...
Start recording input to an RZX file, initialised from the cur-
rent emulation state. You will be prompted for a filename to
use.
File, Recording, Record from snapshot...
Start recording input to an RZX file, initialised from a snap-
shot. You will first be asked for the snapshot to use and then
the file to save the recording to.
File, Recording, Continue recording...
Continue recording input into an existing RZX file from the last
recorded state. Finalised recordings cannot be resumed. You will
be prompted for the recording to continue.
Insert
File, Recording, Insert snapshot
Inserts a snapshot of the current state into the RZX file. This
can be used at a later point to roll back to the inserted state
by using one of the commands below.
Delete
File, Recording, Rollback
Rolls back the recording to the point at which the previous
snapshot was inserted. Recording will continue from that point.
File, Recording, Rollback to...
Roll back the recording to any snapshot which has been inserted
into the recording.
File, Recording, Play...
Playback recorded input from an RZX file. This lets you replay
keypresses recorded previously. RZX files generally contain a
snapshot with the Spectrum's state at the start of the record-
ing; if the selected RZX file doesn't, you'll be prompted for a
snapshot to load as well.
File, Recording, Stop
Stop any currently-recording/playing RZX file.
File, Recording, Finalise...
Compact an RZX file. Any interspersed snapshot will be removed
and the recording cannot be continued. All action replays sub-
mitted to the RZX Archive should be finalised.
File, AY Logging, Record...
Start recording the bytes output via the AY-3-8912 sound chip to
a PSG file. You will be prompted for a filename to save the
recording to.
File, AY Logging, Stop
Stop any current AY logging.
File, Screenshot, Open SCR Screenshot...
Load an SCR screenshot (essentially just a binary dump of the
Spectrum's video memory) onto the current screen. Fuse supports
screenshots saved in the Timex hi-colour and hi-res modes as
well as `normal' Spectrum screens, and will make a simple con-
version if a hi-colour or hi-res screenshot is loaded onto a
non-Timex machine.
File, Screenshot, Save Screen as SCR...
Save a copy of whatever's currently displayed on the Spectrum's
screen as an SCR file. You will be prompted for a filename to
save the screenshot to.
File, Screenshot, Open MLT Screenshot...
Load an MLT screenshot onto the current screen. The MLT format
is similar to the SCR format but additionally supports capturing
images that use techniques to display more than two colours in
each Spectrum attribute square. Fuse will only load the bitmap
version of an image on a Sinclair machine but on a Timex clone
it can show the full colour detail captured in the image by us-
ing the hi-colour mode.
File, Screenshot, Save Screen as MLT...
Save a copy of whatever's currently displayed on the Spectrum's
screen as an MLT file. You will be prompted for a filename to
save the screenshot to.
File, Screenshot, Save Screen as PNG...
Save the current screen as a PNG file. You will be prompted for
a filename to save the screenshot to.
File, Scalable Vector Graphics, Start capture in line mode...
Start trapping the video output functions present in ROM to copy
the picture to SVG files, thus creating vectorized scalable pic-
ture; it is expected to be fully operational in BASIC only, but
few machine code programs could work, if they use the ROM ad-
dresses to output text or graphics. The initial picture size is
256x176, but it is increased everytime a `scroll' happens. On
every CLS a new file will be created, with an increasing se-
quence number. CIRCLEs will be described as a sequence of lines,
so the original `imprecisions' will be still visible. The text
output will be fully understood and decoded: normal ASCII char-
acters will be converted into COURIER scalable fonts, UDG graph-
ics into dot matrix areas, GRAPHICS blocky characters into small
squares. A slightly transparent output permits to show a bit of
the overlapped text and graphics elements. Lower portion of the
screen (normally bound to stream #0 and #1) won't be captured.
File, Scalable Vector Graphics, Start capture in dot mode...
As above, but line capture is disabled. A line will be rendered
as a sequence of dots.
File, Scalable Vector Graphics, Stop capture
Stop the SVG capture function.
File, Movie, Record...
Fuse can record movie (video and audio) into a file with special
format which can be converted later to a common video file for-
mat with the fmfconv(1) utility. You will be prompted for a
filename to save video. Please see MOVIE RECORDING section.
File, Movie, Record from RZX...
Start movie recording and RZX playback at the same time. You
will be prompted for a filename to play from and a filename to
save video.
File, Movie, Pause
Pause movie recording which is currently in progress.
File, Movie, Continue
Resume movie recording which has been previously paused.
File, Movie, Stop
Stop movie recording which is currently in progress.
File, Load Binary Data...
Load binary data from a file into the Spectrum's memory. After
selecting the file to load data from, you can choose where to
load the data and how much data to load.
File, Save Binary Data...
Save an arbitrary chunk of the Spectrum's memory to a file. Se-
lect the file you wish to save to, followed by the location and
length of data you wish to save.
F10
File, Exit
Exit the emulator. A confirmation dialog will appear checking
you actually want to do this.
F4
Options, General...
Display the General Options dialog, letting you configure Fuse.
(With the widget UI, the keys shown in brackets toggle the op-
tions, Enter confirms any changes, and Esc aborts). Note that
any changed settings only apply to the currently-running Fuse.
The options available are:
Emulation speed
Set how fast Fuse will attempt to emulate the Spectrum,
as a percentage of the speed at which the real machine
runs. If your machine isn't fast enough to keep up with
the requested speed, Fuse will just run as fast as it
can. Note that if the emulation speed is faster than
500%, no sound output will be produced.
Frame rate
Specify the frame rate, the ratio of spectrum frame up-
dates to real frame updates. This is useful if your ma-
chine is having trouble keeping up with the spectrum
screen updates.
Issue 2 keyboard
Early versions of the Spectrum used a different value for
unused bits on the keyboard input ports, and a few games
depended on the old value of these bits. Enabling this
option switches to the old value, to let you run them.
Recreated ZX Spectrum
Enable the use of a Recreated ZX Spectrum in `Layer A'
(game) mode. This is a Bluetooth keyboard that can be
paired to the device where Fuse is running.
Use shift with arrow keys
Treat the keyboard arrow keys as shifted like the ZX
Spectrum+ keyboard's arrow keys or as unshifted like a
cursor joystick that maps to the 5, 6, 7 and 8 keys.
Allow writes to ROM
If this option is selected, Fuse will happily allow pro-
grams to overwrite what would normally be ROM. This prob-
ably isn't very useful in most circumstances, especially
as the 48K ROM overwrites parts of itself.
Late timings
If selected, Fuse will cause all screen-related timings
(for example, when the screen is rendered and when memory
contention occurs) to be one tstate later than "normal",
an effect which is present on some real hardware.
Z80 is CMOS
If selected, Fuse will emulate a CMOS Z80, as opposed to
an NMOS Z80. The undocumented `OUT (C),0' instruction
will be replaced with `OUT (C),255' and emulation of a
minor timing bug in the NMOS Z80's `LD A,I' and `LD A,R'
instructions will be disabled.
RS-232 handshake
If you turn this option off, Fuse assumes the RS-232 line
other end is live when you connect the communication
channels. See also the `--rs232-rx' and `--rs232-tx' op-
tions.
Black and white TV
This option allows you to choose whether to simulate a
colour or black and white television. This is effective
only under the GTK, Win32, Xlib and SDL user interfaces:
the others will always simulate a colour TV.
PAL-TV use TV2x effect
This option allows you to choose whether the PAL TV 2x
and higher scalers also reproduce scanlines in the same
way as the TV 2x, TV 3x and Timex TV scalers.
Show statusbar
For the GTK and Win32 UI, enables the statusbar beneath
the display. For the SDL UI, enables the status icons
showing whether the disk and tape are being accessed.
This option has no effect for the other user interfaces.
Snap joystick prompt
If set, Fuse will prompt you which physical joystick or
keyboard you want to connect to the joystick interface
enabled in the snapshot unless it already matches your
current configuration.
Confirm actions
Specify whether `dangerous' actions (those which could
cause data loss, for example resetting the Spectrum) re-
quire confirmation before occurring.
Auto-save settings
If this option is selected, Fuse will automatically write
its currently selected options to its configuration file
on exit (either in xml format if libxml2 was available
when Fuse was compiled or plain text). If this option is
off, you'll have to manually use Options, Save afterwards
to ensure that this setting gets written to Fuse's con-
figuration file. Note that if you turn this option on,
loading a snapshot could enable peripherals that would be
written permanently to the configuration file.
Options, Media...
Display the Media Options dialog, letting you configure Fuse's
tape and Microdrive options. (With the widget UI, the keys shown
in brackets toggle the options, Enter confirms any changes, and
Esc aborts). Note that any changed settings only apply to the
currently-running Fuse.
Auto-load media
On many occasions when you open a tape or disk file, it's
because it's got a program in you want to load and run.
If this option is selected, this will automatically hap-
pen for you when you open one of these files using the
File, Open... menu option -- you must then use the Media
menu to use tapes or disks for saving data to, or for
loading data into an already running program.
Detect loaders
If this option is enabled, Fuse will attempt to detect
when a loading routine is in progress, and then automati-
cally start the virtual tape to load the program in. This
is done by using a heuristic to identify a loading rou-
tine, so is by no means infallible, but works in most
cases.
Phantom typist mode
Specify the keystroke sequence that the "phantom typist"
should use when starting a program loading. Available op-
tions are
Auto
Keyword
Keystroke
Menu
Plus 2A
Plus 3
The first four of these correspond to automatic detection
based on machine model, keyword based entry, keystroke
based entry, and selection from a 128K style menu. Plus
2A and Plus 3 also correspond to selection from a 128K
style menu, but have special handling for games which
need to be loaded with `LOAD ""CODE'. The most likely use
for this option will be use Keystroke if you have changed
the default 48K ROM for one with keystroke entry.
Fastloading
If this option is enabled, then Fuse will run at the
fastest possible speed when the virtual tape is playing,
thus dramatically reducing the time it takes to load pro-
grams. You may wish to disable this option if you wish to
stop the tape at a specific point.
Use tape traps
Ordinarily, Fuse intercepts calls to the ROM tape-loading
routine in order to load from tape files more quickly
when possible. But this can (rarely) interfere with TZX
loading; disabling this option avoids the problem at the
cost of slower (i.e. always real-time) tape-loading.
When tape-loading traps are disabled, you need to start
tape playback manually, by pressing F8 or choosing the
Media, Tape, Play menu item. Fuse also uses tape traps to
intercept the tape-saving routine in the ROM to save tape
files quickly, tapes can also be saved using the Media,
Tape, Record Start menu item.
Accelerate loaders
If this option is enabled, then Fuse will attempt to ac-
celerate tape loaders by "short circuiting" the loading
loop. This will in general speed up loading, but may
cause some loaders to fail.
Use .slt traps
The multi-load aspect of SLT files requires a trap in-
struction to be supported. This instruction is not gener-
ally used except for this trap, but since it's not incon-
ceivable that a program could be wanting to use the real
instruction instead, you can choose whether to support
the trap or not.
MDR cartridge len
This option controls the number of blocks in a new Micro-
drive cartridge. If the value smaller than 10 or greater
than 254 Fuse assumes 10 or 254. Average real capacity
is around 180 blocks (90 Kb).
Random length MDR cartridge
If this option is enabled, Fuse will use a random Micro-
drive cartridge length (around 180 blocks) instead of the
length specified in the MDR cartridge len option.
Options, Sound...
Display the Sound Options dialog, letting you configure Fuse's
sound output. (With the widget UI, the keys shown in brackets
toggle the options, Enter confirms any changes, and Esc aborts).
Note that any changed settings only apply to the currently-run-
ning Fuse.
Sound enabled
Specify whether sound output should be enabled at all.
When this option is disabled, Fuse will not make any
sound.
Loading sound
Normally, Fuse emulates tape-loading noise when loading
from PZXs, TAPs or TZXs in real-time, albeit at a delib-
erately lower volume than on a real Spectrum. You can
disable this option to eliminate the loading noise en-
tirely.
AY stereo separation
By default, the sound output is mono, since this is all
you got from an unmodified Spectrum. But enabling this
option gives you so-called ACB stereo (for sound from the
128 and other clone's AY-3-8912 sound chip).
Force 8-bit
Force the use of 8-bit sound even if 16-bit (the default)
is available. Note that (when the option is enabled) if
8-bit sound isn't available then there will be no sound
at all, so it's best not to use this option unless you
have a specific need for it.
Speaker type
This option allows the emulation of the sound output sys-
tem to be modified. Different choices of speaker limit
the bass and treble response that can be produced from
the machine. Choose between a "TV" type speaker and a
small "Beeper" type speaker that significantly limits
bass and treble response. Choose "Unfiltered" to get un-
modified (but less accurate) sound output.
AY volume
Sets the relative volume of the AY-3-8912 chip from a
range of 0-100%.
Beeper volume
Sets the relative volume of the beeper from a range of
0-100%.
Covox volume
Sets the relative volume of the Covox from a range of
0-100%.
SpecDrum volume
Sets the relative volume of the SpecDrum from a range of
0-100%.
Options, Peripherals, General...
Display the General Peripherals Options dialog, letting you con-
figure the peripherals which Fuse will consider to be attached
to the emulated machine. (With the widget UI, the keys shown in
brackets toggle the options, Enter confirms any changes, and Esc
aborts). Note that any changed settings only apply to the cur-
rently-running Fuse. Also note that any changes that enable and
disable peripherals may result in a hard reset of the emulated
machine.
Kempston joystick
If this option is selected, Fuse will emulate a Kempston
joystick interface (probably the most widely supported
type on the Spectrum). Note that this option is basi-
cally equivalent to plugging the interface itself into a
Spectrum, not to connecting a joystick; this affects how
the Spectrum responds to a read of input port 31. To use
a Kempston joystick in a game, this option must be en-
abled, and you must also select a Kempston joystick the
Options, Joysticks menu.
Kempston mouse
If this option is selected, Fuse will emulate a Kempston
mouse interface.
If you're using Fuse full-screen, your mouse is automati-
cally used as if attached to the Kempston interface. Oth-
erwise, you'll need to click on the Spectrum display in
order to tell Fuse to grab the pointer (and make it in-
visible); to tell Fuse to release it, click the middle
button (or wheel) or press Escape.
With the framebuffer UI, Fuse prefers to use GPM; if this
is not available, it will fall back to built-in PS/2
mouse support. In this mode, it tries /dev/input/mice,
/dev/mouse then /dev/psaux, stopping when it successfully
opens one. The first of these is preferred since (at
least on Linux, with a 2.6-series kernel) any type of
mouse can be used and any connected mouse may be used.
Swap mouse buttons
If this option is enabled, the left and right mouse but-
tons will be swapped when emulating a Kempston mouse.
Fuller Box
If this option is selected, Fuse will emulate a Fuller
Box AY sound and joystick interface. This emulation is
only available for the 16k, 48k and TC2048 machines.
Melodik
If this option is selected, Fuse will emulate a Melodik
AY sound interface. These interfaces and many similar
ones were produced to make the 48K Spectrum compatible
with the same AY music as the 128K Spectrum. This emula-
tion is only available for the 16k, 48k and TC2048 ma-
chines.
Interface 1
If this option is selected, Fuse will emulate the simple
Sinclair Interface 1, and allow Microdrive cartridges to
be connected and disconnected via the Media, Interface 1,
Microdrive menus. It also enables support for the Inter-
face 1 RS-232 interface.
Interface 2
If this option is selected, Fuse will emulate a cartridge
port as found on the Interface 2. Cartridges can then be
inserted and removed via the Media, Cartridge, Inter-
face 2 menu. Note that the Pentagon, Scorpion, Inter-
face 2, ZXATASP and ZXCF all use the same hardware mecha-
nism for accessing some of their extended features, so
only one of these should be selected at once or unpre-
dictable behaviour will occur.
Multiface One
If this option is selected, Fuse will emulate the Roman-
tic Robot Multiface One. Available for 16K, 48K and
Timex TC2048 machines.
Multiface 128
If this option is selected, Fuse will emulate the Roman-
tic Robot Multiface 128. Available for 16K, 48K, Timex
TC2048, 128K, +2 and SE machines.
Multiface 3
If this option is selected, Fuse will emulate the Roman-
tic Robot Multiface 3. Available for +2A, +3 and +3e ma-
chines.
Stealth Multiface One
This option controls the `invisible' or `stealth' mode of
Multiface One, as the physical switch on the side of the
interface.
Emulate printers
If this option is selected, Fuse will emulate a printer.
See the PRINTER EMULATION section for more details.
ZX Printer
If this option is selected, Fuse will emulate the ZX
Printer. See the PRINTER EMULATION section for more de-
tails.
SpeccyBoot interface
If this option is selected, Fuse will emulate a Speccy-
Boot interface which allows booting a ZX Spectrum over an
Ethernet network. See the SpeccyBoot web page at
http://patrikpersson.github.io/speccyboot/ for more de-
tails.
SpecDrum interface
If this option is selected, Fuse will emulate a Cheetah
SpecDrum sound interface. See the World of Spectrum In-
foseek web page at http://www.worldofspectrum.org/infos-
eekid.cgi?id=1000062 for manuals, software and more. This
emulation is only available for the 48k, 128k and TC2048
machines.
Spectranet
If this option is selected, Fuse will emulate the Spec-
tranet interface, which provides an Ethernet interface
for the Spectrum. See the SPECTRANET EMULATION section
for more details.
Spectranet disable
This option controls the state of the Spectranet auto-
matic page-in jumper (J2). See the SPECTRANET EMULATION
section for more details.
TTX2000S
If this option is selected, Fuse will emulate the
OEL/Volex TTX2000S teletext adaptor. Available for the
16K and 48K machines. See the TTX2000S EMULATION section
for more details.
Source
If this option is selected, Fuse will emulate a Currah
Source interface. See the World of Spectrum Infoseek web
page at http://www.worldofspectrum.org/infos-
eekid.cgi?id=1000080 for the manual.
Covox interface
If this option is selected, Fuse will emulate a Covox
digital sound interface. This emulation is only available
for the Pentagon, Pentagon 512k, Pentagon 1024k and Scor-
pion machines. The Pentagon variants use port 0xfb and
the Scorpion version uses port 0xdd.
Options, Peripherals, Disk...
Display the Disk Peripherals Options dialog, letting you config-
ure the disk interface peripherals which Fuse will consider to
be attached to the emulated machine. (With the widget UI, the
keys shown in brackets toggle the options, Enter confirms any
changes, and Esc aborts). Note that any changed settings only
apply to the currently-running Fuse. Also note that any changes
that enable and disable peripherals may result in a hard reset
of the emulated machine.
Simple 8-bit IDE
If this option is selected, Fuse will emulate the simple
8-bit IDE interface as used by the Spectrum +3e, and al-
low hard disks to be connected and disconnected via the
Media, IDE, Simple 8-bit menu.
ZXATASP interface
If this option is selected, Fuse will emulate the ZXATASP
interface, which provides both additional RAM and an IDE
interface. See the ZXATASP AND ZXCF section for more de-
tails.
ZXATASP upload
This option controls the state of the ZXATASP upload
jumper. See the ZXATASP AND ZXCF section for more de-
tails.
ZXATASP write protect
This option controls the state of the ZXATASP write pro-
tect jumper. See the ZXATASP AND ZXCF section for more
details.
ZXCF interface
If this option is selected, Fuse will emulate the ZXCF
interface, which provides both additional RAM and a Com-
pactFlash interface. See the ZXATASP AND ZXCF section for
more details.
ZXCF upload
This option controls the state of the ZXCF upload jumper.
See the ZXATASP AND ZXCF section for more details.
ZXMMC interface
If this option is selected, Fuse will emulate the ZXMMC
interface. Available for +2A, +3 and +3e machines.
DivIDE interface
If this option is selected, Fuse will emulate the DivIDE
interface. See the DIVIDE section for more details.
DivIDE write protect
This option controls the state of the DivIDE write pro-
tection jumper. See the DIVIDE section for more details.
DivMMC interface
If this option is selected, Fuse will emulate the DivMMC
interface. See the DIVMMC section for more details.
DivMMC write protect
This option controls the state of the DivMMC write pro-
tection jumper that prevents flashing the EEPROM chip.
See the DIVMMC section for more details.
+D interface
If this option is selected, Fuse will emulate the +D in-
terface. See the +D EMULATION section for more details.
Didaktik 80 interface
If this option is selected, Fuse will emulate the Didak-
tik 80 (or Didaktik 40) interface. See the DIDAKTIK 80
EMULATION section for more details.
DISCiPLE interface
If this option is selected, Fuse will emulate the DISCi-
PLE interface. See the DISCIPLE EMULATION section for
more details.
Beta 128 interface
If this option is selected, Fuse will emulate the
Beta 128 interface. See the BETA 128 EMULATION section
for more details. Beta 128 emulation is enabled for the
Pentagon and Scorpion machines regardless of this option.
Beta 128 auto-boot in 48K machines
If this option is selected, then when a Beta 128 inter-
face is used in 48K or TC2048 emulation, the machine will
boot directly into the TR-DOS system.
Opus Discovery interface
If this option is selected, Fuse will emulate the Opus
Discovery interface. See the OPUS DISCOVERY EMULATION
section for more details.
Options, RZX...
Display the RZX Options dialog, letting you configure how Fuse's
deals with RZX input recordings. (With the widget UI, the keys
shown in brackets toggle the options, Enter confirms any
changes, and Esc aborts). Note that any changed settings only
apply to the currently-running Fuse.
Create autosaves
If this option is selected, Fuse will add a snapshot into
the recording stream every 5 seconds while creating an
RZX file, thus enabling the rollback facilities to be
used without having to explicitly add snapshots into the
stream. Older snapshots will be pruned from the stream to
keep the file size and number of snapshots down: each
snapshot up to 15 seconds will be kept, then one snapshot
every 15 seconds until one minute, then one snapshot ev-
ery minute until 5 minutes, and then one snapshot every
5 minutes. Note that this "pruning" applies only to auto-
matically inserted snapshots: snapshots manually inserted
into the stream will never be pruned.
Compress RZX data
If this option is selected, and zlib was available when
Fuse was compiled, any RZX files written by Fuse will be
compressed. This is generally a good thing as it makes
the files significantly smaller, and you probably want to
turn it off only if you're debugging the RZX files or
there's some other program which doesn't support com-
pressed RZX files.
Competition mode
Any input recordings which are started when this option
is selected will be made in `competition mode'. In es-
sence, this means that Fuse will act just like a real
Spectrum would: you can't load snapshots, pause the emu-
lation in any way, change the speed or anything that you
couldn't do on the real machine. If any of these things
are attempted, or if the emulated Fuse is running more
than 5% faster or slower than normal Spectrum speed, then
the recording will immediately be stopped.
If libgcrypt was available when Fuse was compiled, then
recordings made with competition mode active will be dig-
itally signed, in theory to `certify' that it was made
with the above restrictions in place. However, this pro-
cedure is not secure (and cannot be made so), so the
presence of any signature on an RZX file should not be
taken as providing proof that it was made with competi-
tion mode active. This feature is included in Fuse
solely as it was one of the requirements for Fuse to be
used in an on-line tournament.
Competition code
The numeric code entered here will be written into any
RZX files made in competition mode. This is another fea-
ture for on-line tournaments which can be used to `prove'
that the recording was made after a specific code was re-
leased. If you're not playing in such a tournament, you
can safely ignore this option.
Always embed snapshot
Specify whether a snapshot should be embedded in an RZX
file when recording is started from an existing snapshot.
Options, Movie...
Display the Movie Options dialog, letting you configure how
Fuse's deals with movie recordings.
Movie compression
This option set the compression level to None, Lossless
or High. (See the MOVIE RECORDING section for more infor-
mation).
Stop recording after RZX ends
If this option is selected, Fuse will stop any movie
recording after an RZX playback is finished.
Options, Joysticks
Fuse can emulate many of the common types of joystick which were
available for the Spectrum. The input for these emulated joy-
sticks can be taken from real joysticks attached to the emulat-
ing machine (configured via the Options, Joysticks, Joy-
stick 1... and Options, Joysticks, Joystick 2... options), or
from the q, a, o, p, and Space keys on the emulating machines
keyboard, configured via the Options, Joysticks, Keyboard...
option. Note that when using the keyboard to emulate a joystick,
the q, a, o, p, and Space keys will not have their normal effect
(to avoid problems with games which do things like use p for
pause when using a joystick).
Each of the joysticks (including the `fake' keyboard joystick)
can be configured to emulate any one of the following joystick
types:
None
No joystick: any input will simply be ignored.
Cursor
A cursor joystick, equivalent to pressing 5
(left), 6 (down), 7 (up), 8 (right), and 0 (fire).
Kempston
A Kempston joystick, read from input port 31. Note
that the Options, Peripherals, General, Kempston
interface option must also be set for the input to
be recognised.
Sinclair 1
Sinclair 2
The `left' and `right' Sinclair joysticks, equiva-
lent to pressing 1 (left), 2 (right), 3 (down), 4
(up), and 5 (fire), or 6 (left), 7 (right), 8
(down), 9 (up), and 0 (fire) respectively.
Timex 1
Timex 2
The `left' and `right' joysticks as attached to
the Timex 2068 variant's built-in joystick inter-
face.
For the real joysticks, it is also possible to configure what
effect each button on the joystick will have: this can be Joy-
stick Fire, equivalent to pressing the emulated joystick's fire
button, Nothing, meaning to have no effect, or any Spectrum key,
meaning that pressing that button will be equivalent to pressing
that Spectrum key.
Options, Select ROMs, Machine ROMs
An individual dialog is available for each Spectrum variant emu-
lated by Fuse which allows selection of the ROM(s) used by that
machine. Simply select the ROM you wish to use, and then reset
the Spectrum for the change to take effect.
Options, Select ROMs, Peripheral ROMs
The same as the Machine ROMs menu, but an individual dialog is
available for peripherals that need a ROM. Simply select the ROM
you wish to use, and then reset the Spectrum for the change to
take effect.
Options, Filter...
Select the graphics filter currently in use. See the GRAPHICS
FILTERS section for more details.
F11
Options, Full Screen
Switch Fuse between full screen and windowed mode. This menu is
only available under the SDL UI.
Options, Disk Options...
When emulating disk drives, Fuse allows the specification of the
physical drive units attached to the emulated interface. Each
drive can be set to be one of the following types:
Disabled
Single-sided 40 track
Double-sided 40 track
Single-sided 80 track
Double-sided 80 track
The Disabled option is not supported for Drive 1 or Drive A of
any interface.
The available options that can be set are:
+3 Drive A
Defaults to a single-sided 40 track drive.
+3 Drive B
Defaults to a double-sided 80 track drive.
+3 Detect Speedlock
Specify whether the +3 drives try to detect Speedlock
protected disks, and emulate `weak' sectors. If the disk
image file (EDSK or UDI) contains weak sector data, than
Speedlock detection is automatically omitted. See also
the WEAK DISK DATA section.
Beta 128 Drive A
Defaults to a double-sided 80 track drive.
Beta 128 Drive B
Defaults to a double-sided 80 track drive.
Beta 128 Drive C
Defaults to a double-sided 80 track drive.
Beta 128 Drive D
Defaults to a double-sided 80 track drive.
+D Drive 1
Defaults to a double-sided 80 track drive.
+D Drive 2
Defaults to a double-sided 80 track drive.
Didaktik 80 Drive A
Defaults to a double-sided 80 track drive.
Didaktik 80 Drive B
Defaults to a double-sided 80 track drive.
DISCiPLE Drive 1
Defaults to a double-sided 80 track drive.
DISCiPLE Drive 2
Defaults to a double-sided 80 track drive.
Opus Drive 1
Defaults to a single-sided 40 track drive.
Opus Drive 2
Defaults to a single-sided 40 track drive.
Try merge 'B' side of disks
This option prompts the user to confirm whether Fuse
should try to merge the `B' side of a disk image from a
separate file when opening a new single-sided disk image.
Confirm merge disk sides
Select whether Fuse should try to merge a separate file
for the `B' side of a disk image separate file when open-
ing a new disk image. Most double sided disk images are
dumped as two single sided disk images e.g. `Golden Axe
- Side A.dsk' and `Golden Axe - Side B.dsk'. So, if we
want to play Golden Axe, first we have to insert the
first disk image and when the game asks to insert side B,
we have to find and open the second disk image, instead
of just `flip'-ing the disk inside the drive. If enabled,
Fuse will try to open the second image too and create a
double sided disk image (merging the two one sided disk
images) and insert this merged virtual disk into the disk
drive. The function detects whether the file is one side
of a double-sided image if the filename matches a pattern
like [Ss]ide[ _][abAB12][ _.] in the file name of a disk
that is being opened. If found, Fuse will try to open the
other side of the disk too substituting the appropriate
characters in the filename e.g. 1->2, a->b, A->B. If
successful then it will merge the two images and now we
have a double sided disk in drive. This means that if we
open `Golden Axe - Side A.dsk', then Fuse will try to
open `Golden Axe - Side B.dsk' too. Now, we can just
`flip' the disk if Golden Axe asks for `Side B'. The
available options are Never, With single-sided drives and
Always.
Options, Save
This will cause Fuse's current options to be written to .fuserc
in your home directory (Unix-like systems), or fuse.cfg in your
%USERPROFILE% folder (Windows), from which they will be picked
up again when Fuse is restarted. The best way to update this
file is by using this option, but it's a simple XML file if
libxml2 was available when Fuse was compiled (otherwise, plain
text), and shouldn't be too hard to edit by hand if you really
want to.
Pause
Machine, Pause
Pause or unpause emulation. This option is available only under
the GTK and Win32 UIs; to pause the other user interfaces, sim-
ply press F1 to bring up the main menu.
F5
Machine, Reset
Reset the emulated Spectrum.
Machine, Hard reset
Reset the emulated Spectrum. A hard reset is equivalent to turn-
ing the Spectrum's power off, and then turning it back on.
F9
Machine, Select...
Choose a type of Spectrum to emulate. An brief overview of the
Sinclair, Amstrad and Timex can be found at
http://www.nvg.ntnu.no/sinclair/computers/zxspectrum/zxspec-
trum.htm while more technical information can be found at
http://www.worldofspectrum.org/faq/reference/reference.htm, and
http://www.worldofspectrum.org/faq/reference/tmxreference.htm.
Spectrum 16K
Spectrum 48K
The original machines as released by Sinclair in 1982
with 16 or 48K of RAM respectively.
Spectrum 48K (NTSC)
The NTSC 48K machine released in limited numbers in parts
of South America.
Spectrum 128K
The 128K machine as released by Sinclair in 1985 (Spain)
or 1986 (UK).
Spectrum +2
The first machine released by Amstrad, in 1986. From an
emulation point of view, the +2 is virtually identical to
the 128K.
Spectrum +2A
Spectrum +3
The two machines released by Amstrad in 1988. Technically
very similar to each other, except that the +3 features a
3 disk drive while the +2A does not.
Spectrum +3e
A +3 with modified ROMs allowing access to IDE hard disks
via the simple 8-bit interface, as activated from the Op-
tions, Peripherals, Disk... dialog. See
http://www.worldofspectrum.org/zxplus3e/ for more de-
tails.
Timex TC2048
Timex TC2068
The variants of the Spectrum as released by Timex in Por-
tugal.
Timex TS2068
The variant of the Spectrum released by Timex in North
America.
Pentagon 128K
Russian clone of the Spectrum. There were many different
machines called Pentagon from 1989 to 2006, this machine
corresponds to a 1991 era Pentagon 128K with the optional
AY sound chip and the integrated Beta 128 disk interface,
and is the version of the machine most often emulated.
More technical details can be found at http://www.world-
ofspectrum.org/rusfaq/index.html,
Pentagon 512K
Pentagon 1024K
Newer versions of the Pentagon Russian Spectrum clones
which incorporate more memory and the "Mr Gluk Reset Ser-
vice" ROM offering a more powerful firmware.
Scorpion ZS 256
Another Russian clone of the Spectrum. Some details can
be found at http://www.worldofspectrum.org/rusfaq/in-
dex.html. Like all the Russian clones, they have built
in 3.5 disk drives, accessed via the Beta 128 disk inter-
face and TR-DOS (the Technology Research Disk Operating
System). The most important distinction from the Penta-
gon 128k and similar machines is the display timing de-
tails.
Spectrum SE
A recent variant designed by Andrew Owen and Jarek
Adamski, which is possibly best thought of as a cross be-
tween the 128K machine and the Timex variants, allowing
272K of RAM to be accessed. Some more details are avail-
able at http://www.worldofspectrum.org/faq/refer-
ence/sereference.htm and documentation of the extended
BASIC is available at https://github.com/cheveron/seba-
sic4/wiki. The bug tracker for the BASIC is at
https://github.com/cheveron/sebasic4/issues?state=open.
Machine, Debugger...
Start the monitor/debugger. See the MONITOR/DEBUGGER section for
more information.
Machine, Poke Finder...
Start the `poke finder'. See the POKE FINDER section for more
information.
Machine, Poke Memory...
Allow one to use multiface POKEs for things such as infinite
lives. See the POKE MEMORY section for more information.
Machine, Memory Browser...
Start the memory browser. It should be fairly obvious what this
does; perhaps the only thing worth noting is that emulation is
paused until you close the window.
Machine, NMI
Sends a non-maskable interrupt to the emulated Spectrum. Due to
a typo in the standard 48K ROM, this will cause a reset, but
modified ROMs are available which make use of this feature. When
the +D (or DISCiPLE) is emulated, this is used to access the +D
(or DISCiPLE)'s screenshot and snapshot features (see the +D EM-
ULATION and DISCIPLE EMULATION sections below). For the DISCi-
PLE, Caps Shift must be held down whilst pressing the NMI but-
ton. For some UIs, this may be tricky, or even impossible to
do. Note that GDOS on the DISCiPLE contains a bug which causes
corruption of saved snapshots, and a failure to return from the
NMI menu correctly. This bug is not present in G+DOS on the +D.
Machine, Multiface Red Button
Presses the Multiface One/128/3 red button to active the inter-
face.
Machine, Didaktik SNAP
Presses the Didaktik 80 (or Didaktik 40)'s `SNAP' button.
F7
Media, Tape, Open...
Choose a PZX, TAP or TZX virtual-tape file to load from. See the
FILE SELECTION section below for details on how to choose the
file. If Auto-load media is set in the Media Options dialog (as
it is by default), you may use the File, Open... menu option
instead, and the tape will begin loading automatically. Other-
wise, you have to start the load in the emulated machine (with
LOAD "" or the 128's Tape Loader option, though you may need to
reset first).
To guarantee that TZX files will load properly, you should se-
lect the file, make sure tape-loading traps are disabled in the
Media Options dialog, then press F8 (or do Media, Tape, Play).
That said, most TZXs will work with tape-loading traps enabled
(often quickly loading partway, then loading the rest real-
time), so you might want to try it that way first.
F8
Media, Tape, Play
Start playing the PZX, TAP or TZX file, if required. (Choosing
the option (or pressing F8) again pauses playback, and a further
press resumes). To explain -- if tape-loading traps have been
disabled (in the Media Options dialog), starting the loading
process in the emulated machine isn't enough. You also have to
`press play', so to speak :-), and this is how you do that. You
may also need to `press play' like this in certain other circum-
stances, e.g. TZXs containing multi-load games may have a stop-
the-tape request (which Fuse obeys).
Media, Tape, Browse
Browse through the current tape. A brief display of each of the
data blocks on the current tape will appear, from which you can
select which block Fuse will play next. With the GTK UI, emula-
tion will continue while the browser is displayed; double-click-
ing on a block will select it. In the other UIs, emulation is
paused and you can use the cursor keys and press Enter to select
it. If you decide you don't want to change block, just press Es-
cape.
Media, Tape, Rewind
Rewind the current virtual tape, so it can be read again from
the beginning.
Media, Tape, Clear
Clear the current virtual tape. This is particularly useful when
you want a `clean slate' to add newly-saved files to, before do-
ing Media, Tape, Write... (or F6).
F6
Media, Tape, Write...
Write the current virtual-tape contents to a TZX file. You will
be prompted for a filename. The virtual-tape contents are the
contents of the previously-loaded tape (if any has been loaded
since you last did a Media, Tape, Clear), followed by anything
you've saved from the emulated machine since. These newly-saved
files are not written to any tape file until you choose this op-
tion!
Media, Tape, Record Start
Starts directly recording the output from the emulated Spectrum
to the current virtual-tape. This is useful when you want to
record using a non-standard ROM or from a custom save routine.
Most tape operations are disabled during recording. Stop record-
ing with the Media, Tape, Write... menu option.
Media, Tape, Record Stop
Stops the direct recording and places the new recording into the
virtual-tape.

Enter.
Help, About...
Show Fuse's version number.
KEY MAPPINGS
When emulating the Spectrum, keys F1 to F10 are used as shortcuts for
various menu items, as described above. The alphanumeric keys (along
with Enter and Space) are mapped as-is to the Spectrum keys. The other
key mappings are:
Shift emulated as Caps Shift
Control, Alt, and Meta
emulated as Symbol Shift (most other modifiers are also mapped
to this)
Backspace
emulated as Caps-0 (Delete)
Esc emulated as Caps-1 (Edit)
Caps Lock
emulated as Caps-2
Cursor keys
emulated as Caps-5/6/7/8 (as appropriate)
Tab emulated as Caps Shift-Symbol Shift (Extended Mode)
Some further punctuation keys are supported, if they exist on your key-
board -- `,', `.', `/', `;', `'', `#', `-', and `='. These are mapped
to the appropriate symbol-shifted keys on the Spectrum.
A list of keys applicable when using the file selection dialogs is
given in the FILE SELECTION section below.
DISPLAY SIZE
Some of Fuse's UIs allow resizing of the emulated Spectrum's display.
For the window-based ones (GTK, Win32 and Xlib), you can resize the
window by, well, resizing it. :-) Exactly how this works depends on
your window manager; you may have to make the window over twice the
width and height of the original size before it actually scales up.
Fuse attempts to keep the window `square', but with some window man-
agers this can mean the window will never resize at all. If you experi-
ence this problem, the `--no-aspect-hint' option may help.
If you're using the SDL UI under X11 or GTK, the window will automati-
cally resize to be the correct size for the graphics filter selected.
GRAPHICS FILTERS
Fuse has the ability to apply essentially arbitrary filters between
building its image of the Spectrum's screen, and displaying it on the
emulating machine's monitor. These filters can be used to do various
forms of smoothing, emulation of TV scanlines and various other possi-
bilities. Support for graphics filters varies between the different
user interfaces, but there are two general classes: the GTK, Win32,
Xlib and SDL user interfaces (and the saving of .png screenshots) sup-
port `interpolating' filters which use a palette larger than the Spec-
trum's 16 colours, while the framebuffer user interface currently does
not support filters at all.
A further complication arises due to the fact that the Timex machines
have their high-resolution video mode with twice the horizontal resolu-
tion. To deal with this, Fuse treats these machines as having a `nor-
mal' display size which is twice the size of a normal Spectrum's
screen, leading to a different set of filters being available for these
machines. Note that any of the double or triple-sizing filters are
available for Timex machines only when using the SDL, Win32 or GTK user
interfaces.
The available filters, along with their short name used to select them
from the command line, are:
Timex half (smoothed) (half)
Timex half (skipping) (halfskip)
Two Timex-machine specific filters which scale the screen down
to half normal (Timex) size; that is, the same size as a normal
Spectrum screen. The difference between these two filters is in
how they handle the high-resolution mode: the `smoothed' version
is an interpolating filter which averages pairs of adjacent pix-
els, while the `skipping' version is a non-interpolating filter
which simply drops every other pixel.
Normal (normal)
The simplest filter: just display one pixel for every pixel on
the Spectrum's screen.
Double size (2x)
Scale the displayed screen up to double size.
Triple size (3x)
Scale the displayed screen up to triple size. Available when
saving screenshots of non-Timex machines.
Quadruple size (4x)
Scale the displayed screen up to quadruple size.
2xSaI (2xsai)
Super 2xSaI (super2xsai)
SuperEagle (supereagle)
Three interpolating filters which apply successively more
smoothing. All three double the size of the displayed screen.
AdvMAME2x (advmame2x)
A double-sizing, non-interpolating filter which attempts to
smooth diagonal lines.
AdvMAME3x (advmame3x)
Very similar to AdvMAME2x, except that it triples the size of
the displayed screen. Available when saving screenshots of non-
Timex machines.
TV 2x (tv2x)
TV 3x (tv3x)
TV 4x (tv4x)
Timex TV (timextv)
Four filters which attempt to emulate the effect of television
scanlines. The first is a double-sizing filter for non-Timex ma-
chines, the second is a similar triple-sizing filter, the third
is a similar quadruple-sizing filter, while the last is a sin-
gle-sizing filter for Timex machines (note that this means TV 2X
and Timex TV produce the same size output).
PAL TV (paltv)
PAL TV 2x (paltv2x)
PAL TV 3x (paltv3x)
PAL TV 4x (paltv4x)
Four filters which attempt to emulate the effect of the PAL TV
system which layers a lower-resolution colour image over the top
of a higher-resolution black-and-white image. The filters can
also optionally add scanlines like the other TV series scalers.
Dot matrix (dotmatrix)
A double-sizing filter which emulates the effect of a dot-matrix
display.
Timex 1.5x (timex15x)
An interpolating Timex-specific filter which scales the Timex
screen up to 1.5x its usual size (which is therefore 3x the size
of a `normal' Spectrum screen).
Timex 2x (timex2x)
A non-interpolating Timex-specific filter which scales the Timex
screen up to 2x its usual size (which is therefore 4x the size
of a `normal' Spectrum screen).
HQ 2x (hq2x)
HQ 3x (hq3x)
HQ 4x (hq4x)
Three filters which do high quality (but slow) antialiasing.
Doubles and triples and quadruples the size of the displayed
screen respectively.
THE EMULATED SPECTRUM
The emulated Spectrum is, by default, an unmodified 48K Spectrum with a
tape player and ZX Printer attached. Oh, and apparently some magical
snapshot load/save machine which is probably best glossed over for the
sake of the analogy. :-)
To emulate different kinds of Spectrum, select the Machine, Select...
menu option, or press F9.
The Spectrum emulation is paused when any dialogs appear. In the widget
UI, it's also paused when menus or the keyboard picture are displayed.
PRINTER EMULATION
The various models of Spectrum supported a range of ways to connect
printers, three of which are supported by Fuse. Different printers are
made available for the different models:
16, 48, TC2048, TC2068, TS2068
ZX Printer
128/+2/Pentagon
Serial printer (text-only)
+2A, +3
Parallel printer (text-only)
If Opus Discovery, +D or DISCiPLE emulation is in use and printer emu-
lation is enabled, text-only emulation of the disk interface's parallel
printer interface is provided.
Any printout is appended to one (or both) of two files, depending on
the printer -- these default to printout.txt for text output, and
printout.pbm for graphics (PBM images are supported by most image view-
ers and converters). These names can be changed with the --textfile and
--graphicsfile options from the command line or configuration file.
While the ZX Printer can only output graphically, simulated text output
is generated at the same time using a crude sort of OCR based on the
current character set (a bit like using SCREEN$). There is currently no
support for graphics when using the serial/parallel output, though any
escape codes used will be `printed' faithfully. (!)
By the way, it's not a good idea to modify the printout.pbm file out-
side of Fuse if you want to continue appending to it. The header needs
to have a certain layout for Fuse to be able to continue appending to
it correctly, and the file will be overwritten if it can't be appended
to.
ZXATASP AND ZXCF
The ZXATASP and ZXCF interfaces are two peripherals designed by Sami
Vehmaa which significantly extend the capabilities of the Spectrum.
More details on both are available from Sami's homepage,
http://user.tninet.se/~vjz762w/, but a brief overview is given here.
The real ZXATASP comes with either 128K or 512K of RAM and the ability
to connect an IDE hard disks and a CompactFlash card, while the ZXCF
comes with 128K, 512K or 1024K of RAM and the ability to connect a Com-
pactFlash card. From an emulation point of view, the two interfaces are
actually very similar as a CompactFlash card is logically just an IDE
hard disk. Currently, Fuse's emulation is fixed at having 512K of RAM
in the ZXATASP and 1024K in the ZXCF.
To activate the ZXATASP, simply select the ZXATASP interface option
from the Options, Peripherals, Disk... dialog. The state of the upload
and write protect jumpers is then controlled by the ZXATASP upload and
ZXATASP write protect options. Similarly, the ZXCF is controlled by the
ZXCF interface and ZXCF upload options (the ZXCF write protect is soft-
ware controlled).
If you're using either the ZXATASP or ZXCF, you almost certainly want
to investigate ResiDOS, the operating system designed for use with the
ZXATASP and ZXCF. ResiDOS provides facilities for using the extra RAM,
accessing the mass storage devices and a task manager allowing virtu-
ally instant switching between programs on the Spectrum. See
http://www.worldofspectrum.org/residos/ for more details.
DIVIDE
The DivIDE is another IDE interface for the Spectrum, of which full de-
tails can be found at http://web.ar-
chive.org/web/20150302052256/http://baze.au.com/divide/. The interface
can be activated via the DivIDE interface option from the Options, Pe-
ripherals, Disk... dialog, and the state of its write protect jumper
controlled via the DivIDE write protect option. If you're going to be
using the DivIDE, you'll probably want one of the firmwares available
from the DivIDE homepage.
DIVMMC
The DivMMC is a MMC interface for the Spectrum. Originally designed by
Alessandro Dorigatti for the V6Z80P+ FPGA board as the fusion of DivIDE
and ZXMMC+ interfaces, later assembled as an interface for real spec-
trums by Mario Prato. Currently there are variants with different RAM
size, one/two memory cards slots, optional kempston jostick, etc.
The interface can be activated via the DivMMC interface option from the
Options, Peripherals, Disk... dialog, and the state of its EEPROM
write protect jumper controlled via the DivMMC write protect option.
If you're going to be using the DivMMC, you'll need to load the ESXDOS
firmware at http://www.esxdos.org/ or use the ZX Spectrum +3e ROMs by
Garry Lancaster.
You'll also need a HDF image to store the contents of the memory card.
There are several tools to create and manipulate this file format,
e.g., hdfmonkey at https://github.com/gasman/hdfmonkey.
SPECTRANET EMULATION
The Spectranet is an Ethernet network interface for the ZX Spectrum by
Dylan Thomas. The interface can be activated via the Spectranet option
on the Peripherals preferences dialog, and the state of its automatic
page-in (disable) jumper controlled via the Spectranet disable option.
If you're going to be using the Spectranet, you'll probably want one of
the firmwares available from the Spectranet homepage (http://spec-
trum.alioth.net/doc/index.php) which is also where you can find more
information on using the interface.
Installing the Spectranet firmware on Fuse is slightly more complicated
than on a real machine, mostly because Fuse's emulation doesn't support
DHCP. These instructions are correct as of 2012-01-26 -- if you're us-
ing a later firmware than this, things may have changed slightly.
The first thing you will need to do is to obtain a copy of the Spec-
tranet installer as a .tap file (or similar). The installer is also
available at the Spectranet site above.
Once you have a copy of the installer, start Fuse and tick the Spec-
tranet option from the Options, Peripherals, General... dialog, and
the state of its write protect jumper controlled via the Spectranet
disable option. Once that's done, open the installer file (use the Me-
dia, Tape, Open... command rather than File, Open... to prevent au-
toloading) and enter the following commands from BASIC:
CLEAR 26999
LOAD "" CODE
RANDOMIZE USR 27000
The screen should turn blue and you'll see around 20 lines of message
appearing as the firmware is installed, starting with "Erasing sector
0" and finishing with "Restoring page B", and you'll get the familiar
0 OK, 0: 1 at the bottom of the screen.
Now untick the Spectranet disable option from the Options, Peripherals,
General... dialog and reset the Spectrum. You should see a very brief
blue status screen, before the regular copyright screen appears with
some Spectranet information at the top -- there should be four status
lines, starting with "Alioth Spectranet" and ending with the Spec-
tranet's IP address (which will be 255.255.255.255 at this stage).
Now trigger an NMI (the Machine / NMI menu option) and you should get a
white on blue Spectranet NMI menu with five options.
Select [A] Configure network settings -- this should lead you to an-
other menu, which will scroll of the top of the screen; don't worry
about this for now.
You'll now need to set various options:
[A] Enable/disable DHCP -- select N
[B] Change IP address -- enter the IP address of the machine you are
running Fuse on.
[C] Change netmask -- enter the appropriate netmask for the IP address
you selected above. If that doesn't mean anything to you, try
255.255.255.0
[D] Change default gateway -- enter the appropriate gateway address.
If you don't know any better, enter the IP address of your router.
[E] Change primary DNS -- enter the address of your DNS server. If you
don't know any better, use Google's public DNS server, 8.8.8.8.
There is no need to change options [F] or [G], but do select:
[H] Change hostname -- enter a hostname for the Spectranet-enabled ma-
chine. It doesn't really matter what you enter here -- it's mostly use-
ful just to replace the junk default name so you can see what you've
entered for the other settings.
Your screen should now look something like this:
Current configuration
---------------------------------------
Use DHCP : No
IP address : 192.168.000.002
Netmask : 255.255.255.000
Default gateway : 192.168.000.001
Primary DNS : 192.168.000.001
Secondary DNS : 255.255.255.255
Hardware address : FF:FF:FF:FF:FF:FF
Hostname : fuse
<menu options>
If everything looks correct, select [I] Save changes and exit (you'll
see a brief "Saving configuration..." message) followed by [E] Exit, at
which point you'll be returned to BASIC.
Now type the following commands:
%cfgnew
%cfgcommit
Which will show the standard 0 OK, 0:1 at the bottom of the screen.
Reset the Spectrum again and you'll see the same four line status dis-
play, but this time with your IP address on the last line.
Congratulations! You have now installed the Spectranet firmware. To
save having to go through all that every time you start Fuse, save a
.szx snapshot at this point, and load that in every time you want to
use the Spectranet.
TTX2000S EMULATION
Fuse supports emulating the OEL/Volex TTX2000S teletext adaptor with
16K and 48K machines.
The interface has four tuning presets and extracts teletext signals
from the vertical blanking interval of the selected television channel.
These teletext signals are emulated by means of a simple TCP socket in-
terface provided by an external server application. An example server
written in Python is available from https://github.com/ZXGuesser/tele-
text-packet-server
The default address for the four packet servers is 127.0.0.1 (loopback
address), ports 19761 to 19764. Connections can also be made to other
computers on a fast LAN by IP address or hostname. Connecting a packet
server via the internet is not recommended.
Only one connection is active at a time. Changing channel preset on the
emulated interface closes any active connection and opens a new connec-
tion to the appropriate server. The same packet server can be set for
multiple tuning presets.
Note that a limitation of the TTX2000S ROM means that it only decodes
the first 12 lines of a teletext signal. This can be fixed by entering
BASIC and executing `POKE 23394,33' then re-entering the teletext ROM
with `RANDOMIZE USR 23500'. Alternatively just use teletext packet
sources with 12 lines per field or fewer.
FILE SELECTION
The way you select a file (whether snapshot or tape file) depends on
which UI you're using. So firstly, here's how to use the GTK file se-
lector.
The selector shows the directories and files in the current directory
in two separate subwindows. If either list is too big to fit in the
window, you can use the scrollbar to see the rest (by dragging the
slider, for example), or you can use Shift-Tab (to move the keyboard
focus to a subwindow) and use the cursor keys. To change directory,
double-click it.
To choose a file to load you can either double-click it, or click it
then click Ok. Or click Cancel to abort.
If you're using the keyboard, probably the easiest way to use the se-
lector is to just ignore it and type in the name. This isn't as irksome
as it sounds, since the filename input box has filename completion --
type part of a directory or file name, then press Tab. It should com-
plete it. If it was a directory, it moves to that directory; if the
completion was ambiguous, it completes as much as possible, and narrows
the filenames shown to those which match. You should press Enter when
you've finished typing the filename, or Esc to abort.
Now, if you're using the widget UI -- the one using the Spectrum font
-- the selector works a bit differently. The files and directories are
all listed in a single two-column-wide window (the directories are
shown at the top, ending in `/') -- the names may be truncated onscreen
if they're too long to fit.
To move the cursor, you can either use the cursor keys, or the Spectrum
equivalents 5/6/7/8, or (similarly) h/j/k/l. For faster movement, the
Page Up, Page Down, Home, and End keys are supported and do what you'd
expect. To select a file or directory, press Enter. To abort, press
Esc.
With both selectors, do bear in mind that all files are shown, whether
Fuse would be able to load them or not.
MONITOR/DEBUGGER
Firstly, note that the vast majority of this section applies only if
you're using the GTK user interface; if you're using one of the widget
user interfaces, you'll get a very basic monitor which shows the cur-
rent values of the registers and allows you to single step through exe-
cution or continue.
If you are using the GTK user interface, Fuse features a moderately
powerful, completely transparent monitor/debugger, which can be acti-
vated via the Machine, Debugger... menu option. A debugger window will
appear, showing the current state of the emulated machine: the top-left
`pane' shows the current state of the Z80 and the last bytes written to
any emulated peripherals. The bottom-left pane lists any active break-
points. Moving right, the next pane shows where the Spectrum's 64K mem-
ory map (the `W?' and `C?' indicate whether each displayed chunk is
writable or contended respectively). Fuse tracks the memory mapping of
the overall address space in 2KB chunks but will summarise the mapped
pages where they are part of the same page of the underlying memory
source (e.g. 8KB page sizes in the Spectrum 128K and 4KB pages in the
Timex clones' DOCK and EXROM banks).
The next pane to the right has a disassembly, which by default starts
at the current program counter, although this can be modified either by
the `disassemble' command (see below) or by dragging the scrollbar next
to it. The next pane shows the current stack, and the final pane any
`events' which are due to occur and could affect emulation. Any of
these panes can be removed by use of the View menu. Below the displays
are an entry box for debugger commands, and five buttons for control-
ling the debugger:
Evaluate
Evaluate the command currently in the entry box.
Single Step
Run precisely one Z80 opcode and then stop emulation again.
Continue
Restart emulation, but leave the debugger window open. Note that
the debugger window will not be updated while emulation is run-
ning.
Break
Stop emulation and return to the debugger.
Close
Close the debugger window and restart emulation.
Double-clicking on an entry in the stack pane will cause emulation to
run until the program counter reaches the value stored at that address,
while double-clicking on an entry in the `events' pane will cause emu-
lation to run until that time is reached.
The main power of the debugger is via the commands entered into the en-
try box, which are similar in nature (but definitely not identical to
or as powerful as) to those in gdb(1). In general, the debugger is
case-insensitive, and numbers will be interpreted as decimal, unless
prefixed by either `0x' or `$' when they will be interpreted as hex.
Each command can be abbreviated to the portion not in curly braces.
ba{se} number
Change the debugger window to displaying output in base number.
Available values are 10 (decimal) or 16 (hex).
br{eakpoint} [address] [if condition]
Set a breakpoint to stop emulation and return to the debugger
whenever an opcode is executed at address and condition evalu-
ates true. If address is omitted, it defaults to the current
value of PC.
br{eakpoint} p{ort} (re{ad}|w{rite}) port [if condition]
Set a breakpoint to trigger whenever IO port port is read from
or written to and condition evaluates true.
br{eakpoint} (re{ad}|w{rite}) [address] [if condition]
Set a breakpoint to trigger whenever memory location address is
read from (other than via an opcode fetch) or written to and
condition evaluates true. Address again defaults to the current
value of PC if omitted.
br{eakpoint} ti{me} time [if condition]
Set a breakpoint to occur time tstates after the start of the
every frame, assuming condition evaluates true (if one is
given).
br{eakpoint} ev{ent} area:detail [if condition]
Set a breakpoint to occur when the event specified by area:de-
tail occurs and condition evaluates to true. The events which
can be caught are:
beta128:page
beta128:unpage
The Beta 128 interface is paged into or out of memory re-
spectively.
didaktik80:page
didaktik80:unpage
The Didaktik 80 interface is paged into or out of memory
respectively.
disciple:page
disciple:unpage
The DISCiPLE interface is paged into or out of memory re-
spectively.
divide:page
divide:unpage
The DivIDE interface is paged into or out of memory re-
spectively.
divmmc:page
divmmc:unpage
The DivIDE interface is paged into or out of memory re-
spectively.
if1:page
if1:unpage
The Interface 1 shadow ROM is paged into or out of mem-
ory.
multiface:page
multiface:unpage
The Multiface One/128/3 is paged into or out of memory
respectively.
opus:page
opus:unpage
The Opus Discovery is paged into or out of memory respec-
tively.
plusd:page
plusd:unpage
The +D interface is paged into or out of memory respec-
tively.
rzx:end
An RZX recording finishes playing.
speccyboot:page
speccyboot:unpage
The SpeccyBoot interface is paged into or out of memory.
spectranet:page
spectranet:unpage
The Spectranet interface is paged into or out of memory.
tape:play
tape:stop
The emulated tape starts or stops playing.
zxatasp:page
zxatasp:unpage
The ZXATASP interface is paged into or out of memory.
zxcf:page
zxcf:unpage
The ZXCF interface is paged into or out of memory.
In all cases, the event can be specified as area:* to catch all
events from that area.
cl{ear} [address]
Remove all breakpoints at address or the current value of PC if
address is omitted. Port read/write breakpoints are unaffected.
com{mmands} id <newline>
<debugger command> <newline>
<debugger command> <newline>
...
end
Set things such that the specified debugger commands will be au-
tomatically executed when breakpoint id is triggered. There is
currently no user interface for entering multi-line debugger
commands, so the only way to specify this command is on the com-
mand-line via the --debugger-command option.
cond{ition} id [condition]
Set breakpoint id to trigger only when condition is true, or un-
conditionally if condition is omitted.
co{ntinue}
Equivalent to the Continue button.
del{ete} [id]
Remove breakpoint id, or all breakpoints if id is omitted.
di{sassemble} address
Set the centre panel disassembly to begin at address.
ex{it} [expression]
Exit the emulator immediately, using the exit code resulting
from the evaluation of expression, or 0 if expression is omit-
ted.
fi{nish}
Exit from the current CALL or equivalent. This isn't infallible:
it works by setting a temporary breakpoint at the current con-
tents of the stack pointer, so will not function correctly if
the code returns to some other point or plays with its stack in
other ways. Also, setting this breakpoint doesn't disable other
breakpoints, which may trigger before this one. In that case,
the temporary breakpoint remains, and the `continue' command can
be used to return to it.
i{gnore} id count
Do not trigger the next count times that breakpoint id would
have triggered.
n{ext}
Step to the opcode following the current one. As with the `fin-
ish' command, this works by setting a temporary breakpoint at
the next opcode, so is not infallible.
o{ut} port value
Write value to IO port port.
pr{int} expression
Print the value of expression to standard output.
se{t} address value
Poke value into memory at address.
se{t} $variable value
Set the value of the debugger variable variable to value.
se{t} area:detail value
Set the value of the system variable area:detail to value. The
available system variables are listed below.
s{tep}
Equivalent to the Single Step button.
t{breakpoint} [options]
This is the same as the `breakpoint' command in its various
forms, except that the breakpoint is temporary: it will trigger
once and once only, and then be removed.
Addresses can be specified in one of two forms: either an absolute ad-
dresses, specified by an integer in the range 0x0000 to 0xFFFF or as a
`source:page:offset' combination, which refers to a location offset
bytes into memory bank page, independent of where that bank is cur-
rently paged into memory. RAM and ROM pages are indicated, respec-
tively, by `RAM' and `ROM' sources (e.g. offset 0x1234 in ROM 1 is
specified as `ROM:1:0x1234'). Other available sources are: `Betadisk',
`Didaktik 80 RAM', `Didaktik 80 ROM', `DISCiPLE RAM', `DISCiPLE ROM',
`DivIDE EPROM', `DivIDE RAM', `DivMMC EPROM', `DivMMC RAM', `If1',
`If2', `Multiface RAM', `Multiface ROM', `Opus RAM', `Opus ROM', `PlusD
RAM', `PlusD ROM', `SpeccyBoot', `Spectranet', `Timex Dock', `Timex
EXROM', `uSource', `ZXATASP' and `ZXCF'. Please, note that spaces in
memory sources should be escaped, e.g., `break Didak-
tik\ 80\ ROM:0:0x1234'. The 48K machines are treated as having a per-
manent mapping of page 5 at 0x4000, page 2 at 0x8000 and page 0 at
0xC000; the 16K Spectrum is treated as having page 5 at 0x4000 and no
page at 0x8000 and 0xC000.
Anywhere the debugger is expecting a numeric value, except where it ex-
pects a breakpoint id, you can instead use a numeric expression, which
uses a restricted version of C's syntax; exactly the same syntax is
used for conditional breakpoints, with `0' being false and any other
value being true. In numeric expressions, you can use integer constants
(all calculations are done in integers), system variables, debugger
variables, parentheses, the standard four numeric operations (`+', `-',
`*' and `/'), the (non-)equality operators `==' and `!=', the compari-
son operators `>', `<', `>=' and `<=', bitwise and (`&'), or (`|') and
exclusive or (`^') and logical and (`&&') and or (`||'). Square brack-
ets (`[' and `]') can be used to dereference a value; for example
`[0x4000]' will give the value of the first byte of the screen.
System variables are specified via an `area:detail' syntax. The avail-
able system variables are:
ay:current
The current AY-3-8912 register.
divmmc:control
The last byte written to DivMMC control port.
spectrum:frames
The frame count since reset. Note that this variable can only be
read, not written to.
tape:microphone
The current level of the tape input connected to the `EAR' port.
Note that this variable can only be read, not written to.
ula:last
The last byte written to the ULA. Note that this variable can
only be read, not written to.
ula:mem1ffd
The last byte written to memory control port used by the ZX
Spectrum +2A/3; normally addressed at 0x1ffd, hence the name.
ula:mem7ffd
The last byte written to primary memory control port used by the
ZX Spectrum 128 and later; normally addressed at 0x7ffd, hence
the name.
ula:tstates
The number of tstates since the last interrupt.
z80: register name
The value of the specified register. Both 8-bit registers and
16-bit register pairs are supported. The MEMPTR / WZ hidden reg-
ister is also supported. The (presumable) Q hidden register is
also supported.
z80:im
The current interrupt mode of the Z80.
z80:iff1
z80:iff2
1 if the specified interrupt flip-flop is currently set, or 0 if
it is not set.
THE POKE FINDER
The `poke finder' is a tool which is designed to make the task of find-
ing (infinite lives etc.) pokes for games a bit easier: it is similar
to the `Lifeguard' utility which was available for use with the Multi-
face. It works by maintaining a list of locations in which the current
number of lives (etc.) may be stored, and having the ability to remove
from that list any locations which don't contain a specified value.
The poke finder dialog contains an entry box for specifying the value
to be searched for, a count of the current number of possible locations
and, if there are less than 20 possible locations, a list of the possi-
ble locations (in `page:offset' format). The five buttons act as fol-
lows:
Incremented
Remove from the list of possible locations all addresses which
have not been incremented since the last search.
Decremented
Remove from the list of possible locations all addresses which
have not been decremented since the last search.
Search
Remove from the list of possible locations all addresses which
do not contain the value specified in the `Search for' field.
Reset
Reset the poke finder so that all locations are considered pos-
sible.
Close
Close the dialog. Note that this does not reset the current
state of the poke finder.
Double-clicking on an entry in the list of possible locations will
cause a breakpoint to be set to trigger whenever that location is writ-
ten to.
An example of how to use this may make things a bit clearer. We'll use
the 128K version of Gryzor. Load the game, define keys to suit and
start playing. Immediately pause the game and bring up the poke finder
dialog. We note that we currently have 6 lives, so enter `6' into the
`Search for' field and click `Search'. This reduces the number of pos-
sible locations to around 931 (you may get a slightly different number
depending on exactly when you paused the game). Play along a bit and
then (deliberately) lose a life. Pause the game again. As we now have
5 lives, replace the `6' in the `Search for' field with a `5' and click
`Search' again. This then reduces the list of possible locations to
just one: page 2, offset 0x00BC. This is the only location in memory
which stored `6' when we had 6 lives and `5' when we had 5 lives, so
its pretty likely that this is where the lives count is stored. Double-
clicking on the `2:0x00BC' entry in the dialog will set the appropriate
breakpoint (you may wish to open the debugger at this point to confirm
this). Play along a bit more. When you next lose a life, emulation is
stopped with PC at 0x91CD. Scrolling up a few addresses in the debug-
ger's disassembly pane shows a value was loaded from 0x80BC (our hypo-
thetical lives counter), decremented and then stored again to 0x80BC,
which looks very much like the code to reduce the number of lives. We
can now use the debugger to replace the decrement with a NOP (`set
0x91c9 0'), and playing the game some more after this reveals that this
has worked and we now have infinite lives.
THE POKE MEMORY
Fuse supports multiface POKEs, allowing to modify specific memory ad-
dresses in order to cheat (infinite lives, infinite ammo, etc.).
The `poke memory' dialog contains a list of recently loaded POKEs and
some entry boxes for adding custom POKEs:
Bank
Sets the 128K memory bank (values `0' to `7') or the current
memory mapping (value `8' or blank).
Address
Memory address to modify. Values in range 16384 to 65535 for 48K
memory mode or 0 to 65535 for 128K memory banks. GTK UI also ac-
cepts hex addresses.
Value
New value for the former address, in range 0 to 255. Value 256
means "Prompt to the user later".
It is possible to load POKEs from an external file using the File,
Open... menu option or the drag-and-drop functionality in the GTK and
Win32 UIs. After loading a snapshot or tape, Fuse will try to automat-
ically locate a POK file with the same file name. This means that if we
open `GAME.TAP', then Fuse will try to open `GAME.POK' and
`POKES/GAME.POK'. See http://www.worldofspectrum.org/POKformat.txt for
more details about this file format.
POKEs loaded in the list can be activated or deactivated as the user
wants and will remain in memory until a machine reset.
THE .DSK FORMAT
In general, disk images for the +3 Spectrum are thought of as being in
DSK format. However, this is actually a slight oversimplification;
there are in fact two similar, but not identical, DSK formats. (The
difference can be seen by doing `head -1 dskfile': one format will
start `MV - CPCEMU' and the other will start `EXTENDED').
Fuse supports both the `CPCEMU' and `EXTENDED' formats.
BETA 128 EMULATION
Fuse supports Betadisk emulation in its Pentagon and Scorpion emula-
tion, and also under 48K, TC2048, 128K and +2 (but not +2A) emulation
if the Beta 128 interface option from the Options, Peripherals, Disk...
dialog is enabled. When that option is used in 48K or TC2048 emulation
the Beta 128 auto-boot in 48K machines option additionally controls
whether the machine boots directly into the TR-DOS system. See the DISK
FILE FORMATS section for more details on supported disk file formats.
OPUS DISCOVERY EMULATION
By default, Fuse emulates the Opus Discovery interface with the op-
tional 2k RAM expansion and a second 40 track single sided disk drive.
See the DISK FILE FORMATS section for more details on supported disk
file formats. The Opus Discovery's printer port is also emulated for
output only. (See the PRINTER EMULATION section for more details.) The
Opus Discovery may only be used with 16K, 48K, 128K, TC2048 and +2 (not
+2A) emulation. To access disks, use the same syntax as Interface 1
and Microdrives.
+D EMULATION
Fuse supports emulating the +D disk and printer interface. See the DISK
FILE FORMATS section for more details on supported disk file formats.
The +D's printer port is emulated. (See the PRINTER EMULATION section
for more details.) The +D may only be used with 48K, 128K and +2 (not
+2A) emulation. To access disks, you will first need to load G+DOS, by
inserting a disk containing the DOS file (+SYS) and entering "RUN".
Once DOS is loaded, you can load to/from +D disks by prefixing file-
names with `dn' where `n' is the number of the drive in use. For exam-
ple, `LOAD d1"myfile"' would load the file named `myfile' from the emu-
lated drive 1. Microdrive syntax may also be used.
To save a snapshot, choose the Machine, NMI menu option, and then press
`4' to save a 48K snapshot, or `5' to save a 128K snapshot. When sav-
ing a 128K snapshot, you must then press Y or N to indicate whether the
screen changed while saving the snapshot, to finish saving. You can
also choose `3' to save a screenshot to disk. Holding Caps Shift to-
gether with any of these options will cause the +D to save to the
`other' drive to the one used last.
Options `1' and `2' allow screenshots to be printed (in monochrome, in
normal and large formats respectively) if printer emulation is enabled.
For saving and loading of snapshots, and saving of screenshots to disk,
G+DOS must be loaded first, but printing of screenshots can be per-
formed without loading G+DOS.
Finally, `X' will return from the NMI menu.
DIDAKTIK 80 EMULATION
Fuse supports Didaktik 80 (and Didaktik 40) emulation. It emulates the
original version of the Didaktik 80, running MDOS 1 and with a WD2797
floppy controller. See the DISK FILE FORMATS section for more details
on supported disk file formats. The Didaktik 80 may only be used with
16K, 48K and TC2048 emulation. To press the Didaktik 80's `SNAP' but-
ton, choose the Machine, Didaktik SNAP menu option.
DISCIPLE EMULATION
Fuse supports emulating the DISCiPLE disk and printer interface, al-
though it does not currently support emulation of the Sinclair Network,
or support emulation of a DISCiPLE attached to a 128K machine. See the
DISK FILE FORMATS section for more details on supported disk file for-
mats, which are the same as for +D emulation as described above. The
DISCiPLE's printer port is emulated. (See the PRINTER EMULATION section
for more details.) The DISCiPLE may only be used with 48K emulation at
present. To access disks, you will first need to load GDOS, by insert-
ing a disk containing the DOS file (SYS) and entering "RUN". Once DOS
is loaded, you can load to/from DISCiPLE disks by prefixing filenames
with `dn' where `n' is the number of the drive in use. For example,
`LOAD d1"myfile"' would load the file named `myfile' from the emulated
drive 1. Microdrive syntax may also be used.
Snapshots can be saved in a similar manner to that of the +D as de-
scribed above, but note that GDOS on the DISCiPLE contains a bug which
causes corruption as soon as the NMI button is pressed, affecting sav-
ing of snapshots, and also loading of snapshots that were originally
saved with a +D or SAM Coup. This will cause corruption even when a
screenshot is printed, or if the menu is never even entered in the
first place (due to Caps Shift not being pressed down, as is required
for the DISCiPLE), provided that GDOS is loaded. This bug is not
present in G+DOS on the +D. (Note: this was caused by saving/restoring
the AF register twice in the NMI handler, where both AF and the AF'
shadow register should have been saved/restored.)
The NMI button works slightly differently on the DISCiPLE than on the
+D. Caps Shift must be held down whilst pressing the NMI button, and
there is no `X' option to exit the menu. Also, printing of screenshots
requires GDOS to be loaded. Depending on the UI that you're using,
holding down Caps Shift whilst choosing the Machine, NMI menu option
may be slightly tricky, or even impossible. For the GTK UI, ensure
that the Shift key is held before entering on the Machine menu. For
the widget UI, it does not seem possible to perform this action.
DISK FILE FORMATS
Fuse supports several disk image formats in its +D, Didaktik, DISCiPLE
and Beta 128 emulation.
For reading:
.UDI
Ultra Disk Image; for specification please see
http://faqwiki.zxnet.co.uk/wiki/UDI_format or http://zx-
mak.chat.ru/docs.htm
This is the only image format which can store all the relevant
information of the recorded data on a magnetic disk, so it can
be used for any non standard disk format. Fuse can read all ex-
tended track types too (mixed FM/MFM, or tracks with `WEAK' data
or even compressed tracks too).
.FDI
UKV Spectrum Debugger disk image format.
.MGT .IMG
DISCiPLE/+D file formats.
.SAD
For compatibility with SAM Coup disk images using these formats.
Note that SAM Coup `.DSK' images share the same format as
`.MGT'.
.D80 .D40
Didaktik 80 and Didaktik 40 file formats.
.TRD
TR-DOS disk image. TRD and SCL sectors are loaded interleaved,
therefore you might experience problems with TR-DOS ROMs that
use the turbo format (sequential sectors); for detailed informa-
tion please see http://web.ar-
chive.org/web/20070808150548/http://www.ram-
soft.bbk.org/tech/tr-info.zip
.SCL
A simple archive format for TR-DOS disk files. For specification
please see http://www.zx-modules.de/fileformats/sclformat.html
.TD0
Teledisk image format; Fuse supports only files which do not use
the "Advanced Compression" option. Detailed description found in
http://www.classiccmp.org/dunfield/img54306/td0notes.txt and
https://web.ar-
chive.org/web/20130116072335/http://www.fpns.net/willy/wteledsk.htm
.DSK
CPC disk image format; Fuse supports the plain old and the new
extended CPC format too. Further information please see the THE
.DSK FORMAT section and the CPCEMU manual section 7.7.1
http://www.cpc-emu.org/linux/cpcemu_e.txt or the
http://www.cpctech.org.uk/docs/extdsk.html
.OPD .OPU
Opus Discovery file formats.
Fuse supports most of the above formats for writing: .UDI .FDI .MGT
.IMG .SAD .D80 .D40 .TRD .SCL .OPD .OPU .DSK (only the old CPC format).
You can save disk images with any output format, just select the appro-
priate extension. (e.g. `elite3.udi' to save as an UDI file). If the
appropriate libraries were available when libspectrum(3) was compiled,
than Fuse will try to create UDI images with compressed tracks to save
disk space. There is a .LOG `image' format for debugging purpose. This
is a plain text file that contains three dumps of the loaded disk image
at different details. Not all image formats can store all disk images.
You cannot save a disk image with an inappropriate format that loses
some information (e.g. variable track length or sector length).
WEAK DISK DATA
Some copy protections have what is described as `weak/random' data.
Each time the sector is read one or more bytes will change, the value
may be random between consecutive reads of the same sector. Two disk
image formats (Extended DSK and UDI) can store this type of data. Fuse
can read and use weak sector data from EDSK and UDI files when present,
and can save back weak sector data to UDI image format.
MOVIE RECORDING
Fuse can save movies with sound in a specific file format (FMF). This
recording is very fast, and has a moderate size, but you need to use
the fmfconv(1) program in fuse-utils(1) to convert into regular video
and/or audio files. The --movie-compr option allows you to set the
compression level to None, Lossless or High. If zlib(3) is not avail-
able, only None is valid. The default when Zlib is available is Loss-
less. Recording a movie may slow down emulation, if you experience
performance problems, you can try to set compression to None.
Fuse records every displayed frame, so by default the recorded file has
about 50 video frame per second. A standard video has about 24-30/s
framerate, so if you set Options/General/Frame rate 1:n or the equiva-
lent --rate command line option to 2 than recording frame rate reduces
about 25/s. The exact frame rate depends on the Z80 clock frequency
which varies depending on the specific emulated machine.
Note: You can see all of the "gfx" effects only if the Fuse frame rate
option is set to 1, but in most cases you can safely use 2. Also, movie
recording stops if the emulated machine is changed.
The recorded sound sampling rate and the channel number is equal with
the Fuse generated sound sampling rate (44100 Hz by default) and chan-
nel number (mono by default). The common sampling frequencies in stan-
dard video files are 44100 Hz and 48000 Hz. If you use --sound-freq
command line option you can change the frequency.
You can record stereo sound if you use AY stereo separation or the
equivalent --separation command line switch.
You can use fmfconv(1) to convert recorded movie file into a standard
video file.
Examples
fuse --movie-start output.fmf --rate 2 --sound-freq 44100 --separation
ACB
start video recording about 25/s video frame rate and 44100 Hz sampling
frequency stereo sound default compression level.
COMPRESSED FILES
Assuming the appropriate libraries were available when libspectrum(3)
was compiled, snapshots, tape images, dock cartridges and input record-
ing files (RZX) can be read from files compressed with bzip2(3),
gzip(3) or zip(3) just as if they were uncompressed. In the zip case,
only the first supported file found inside the archive is loaded.
There is currently no support for reading compressed +3, DISCiPLE/+D or
Beta disk images.
BUGS
The poke finder can't search outside `normal' RAM.
The libao file output devices not work properly with the GTK UI. No
error reporting, but the created file does not contain any sound data.
If you use a `weak' machine alsa09 makes a lot of clicks and pops and
will output `ALSA: underrun, at least 0ms.' error messages.
