What was done
This project provides a work-in-progress decompilation of the Ratatouille (Jan 18, 2006 prototype) for GameCube. It uses LLM assistance to generate code, which is then verified against original binaries to ensure byte-identical matching.
The project is a work-in-progress decompilation of the Ratatouille (Jan 18, 2006 prototype) for the GameCube. The author reports that code decompiled before October 21, 2026, was completed by hand. Subsequent work is AI-assisted, where an LLM generates code that is then reviewed and checked against the original binaries. The README documents that while the resulting code is byte-identical to the original, elements such as names, types, and source structure beyond what debug information provides may be guesses. Supported versions include DEBUG, RELEASE, MASTERDEBUG, and MASTER. The build process requires an existing copy of the game to extract necessary ELF files. The project uses objdiff for verifying matches. Recent commits indicate the use of Claude for matching specific files like xMath.cpp and xMemoryManagerFixed.cpp. The repository is available at https://raw.githubusercontent.com/seilc/rat/HEAD/README.md.
Reproduce it
Clone the repository, extract game files to orig/RELSAB using Dolphin Emulator, configure with 'python configure.py -v VERSION' (where VERSION is DEBUG, RELEASE, MASTERDEBUG, or MASTER), and run 'ninja'.
