A decompilation toolkit for The Coffin of Andy and Leyley.
To run the compiled binaries, you need the .NET 8.0 Runtime to be installed.
You need a Node.js installation to use the deobfuscator.
Place the program and the llama folder in the main directory that contains Game.exe and run LlamaToolkit from the command line.
LlamaToolkit <mode> <arguments>
Only .k9a files can be decrypted. The filenames of all encrypted files must be unchanged.
Arguments:
inputFileOrDir: Specify the input directory or file. If directory, it will traverse all folders in the directory recursively.
outputDir: Specify the output directory.
You must pass both arguments at once. Both relative and absolute paths are supported.
If no arguments are provided, LlamaToolkit will only check the audio, data, and img folders in the game directory.
LlamaToolkit decrypt <inputFileOrDir> <outputDir>
Allows the game to be launched without Steam.
Arguments:
gameDir: Specify the game directory.
If no arguments are provided, LlamaToolkit will assume that it is currently inside of the game directory.
LlamaToolkit dedrm <gameDir>
Go to the llama/decode-js folder and use npm i to install dependencies.
Then run the command:
LlamaToolkit autopwn <gameDir>
If no arguments are provided, LlamaToolkit will assume that it is currently inside of the game directory.
This command will carry out the following operations:
- Inject the code extractor into the game.
- Launch the game and dump obfuscated code to
input.js. - Kill the game.
- Remove the code extractor from the game.
- Deobfuscate the code in
input.jsand save it tooutput.js.
Restore the DRM.
LlamaToolkit redrm <gameDir>
Acquire the obfuscated game code by injecting a script into the game:
LlamaToolkit extract <gameDir>
The game will dump obfuscated code to a new file named input.js on the next startup.
Run the deobfuscator on this file:
LlamaToolkit deob input.js
The new file will be saved to output.js.
Remove the code extractor from the game:
LlamaToolkit restore <gameDir>
LlamaToolkit uses the Jering.Javascript.NodeJS package, which has its own license.
The deobfuscator uses decode-js, which is licensed under the MIT License.
