This repo provides a simple extension that integrates the build of a Virtual Console .cia file to the pret pokemon Gen I / II repos, to ease the building of a VC .cia for your ROM Hack down to something as simple as make cia.

• A recent pokecrystal, pokegold, pokered, or pokeyellow installation, that supports building Virtual Console patches.
• An original (encrypted or decrypted) .cia file.
• ctrtool and makerom (Only master has been tested)
• Obtain seeddb.bin, here is a link: seeddb.bin

Obtaining the original file is outside of the scope of this document. It can be legally obtained by extracting it from your console through tools such as GodMode9 and/or FunkyCIA.

Run make to build both ctrtool and makerom, and put them in your $PATH.

To install, you need to clone the poke-cia repo into your Pret repository. The following is a pokecrystal example:

cd <path to pokecrystal>
git clone https://github.com/vulcandth/poke-cia poke-cia
echo "-include poke-cia/cia.mk" >> Makefile

Next you will need to create your poke-cia/cia-config.mk file by using poke-cia/cia-config.mk.template as a base.

cp ./poke-cia/cia-config.mk.template ./poke-cia/cia-config.mk

Modify your /poke-cia/cia-config.mk file using a text editor of your choice, adjusting the following line to match the pret repository your are using. In this example we are using pret/pokecrystal

vc_name       := $(vc_crystal_name)

Copy your original dumped .cia files to poke-cia/<build_name>.orig.cia. Where <build_name> represents the names of the .gbc files that is output from your installed pret repository. In the case of Pokemon Crystal, it should be:

poke-cia/pokecrystal11.orig.cia

Finally place your obained seeddb.bin file inside your poke-cia directory.

Now you can run make cia and be on your merry way!
