A toolbox to work with League of Legends game files and export files for CDragon. It can be used as a library or a command-line tool.

To install dependencies, run:

pip install -r requirements.txt

Windows users: precompiled packages can be found here.

The CLI interface allows:

• download game files and list relations between
• list and extract content of WAD files
• export game files to be served by CDragon

Here are some examples, use python3 -m cdragontoolbox -h for details.

# download and extract files for the latest patch to the directory `cdn`
# (files from the new patcher will be used)
python3 -m cdragontoolbox -v download -s patcher:cdn patch=

# same, but don't download language-specific files
python3 -m cdragontoolbox download -s patcher:cdn --no-lang patch=

# list patch versions (using already downloaded data in `cdn/`)
python3 -m cdragontoolbox versions -s cdn/ patch

# list game files for patch 9.9
python3 -m cdragontoolbox files -s cdn/ game=9.9

# extract a WAD file
python3 -m cdragontoolbox wad-extract path/to/assets.wad

# list content of a WAD file
python3 -m cdragontoolbox wad-list path/to/assets.wad

# export files of patch 7.23 into export/7.23
python3 -m cdragontoolbox export -o export 7.23

# export files from PBE
python3 -m cdragontoolbox export --cdn pbe --full main

Solutions are the top-level components downloaded by the patcher. They are located under the solutions/ directory. Currently, two solutions are used: league_client_sln for the LCU and lol_game_client_sln for the in-game client.

Each solution version is located under solutions/{name}/releases/{version}.

Each solution version depends on several projects: a main project and additional projects for each available language. They are located under the projects/ directory. Projects are actually named after the solution, and suffixed by the language code if any. For instance: league_client_en_gb.

Each project version is located under projects/{name}/releases/{version}.

When a project is updated, only files that have changed since the previous version are located under this version directory. Files reused from a previous version stay in this version directory. As a result, downloading the latest version of a project actually download files of previous project versions too.

A patch version is the version used publicly by Riot (for instance 7.23) and retrieved from downloaded files

Patch version changes independently from solution and project versions.

Note: PBE use a single patch version: main.

WADs are archives used by the clients. They contain assets, game data (e.g. item description), files for the LCU interface and more.

Paths of files in WAD files are hashed, they are not stored in clear in the archive. A large number of these hashes have been guessed but there are still a lot of unresolved hashes.

An hash list is provided and regularly updated with new hashes as they are discovered, especially after client updates.

PBE and Korean game files have their own download URLs. Use --cdn pbe or --cdn kr to fetch PBE or Korean files.

Note that they should not be mixed with files from the default CDN. By default, PBE files are downloaded to RADS.pbe and Korean files to RADS.kr.
