What was done #
An ongoing research project to reconstruct the first-party code of Rally Trophy 1.01 using AI-assisted C++ coding agents and byte-exact matching against the original Windows executable.
The Rally Trophy Decomp project is an ongoing effort to reconstruct the first-party C++ source code of the game Rally Trophy 1.01 for Windows. The project utilizes AI coding agents operating under human direction to generate the source code. Correctness is verified through a byte-exact matcher that compares locally compiled object code against the shipped executable, rather than through manual source review. The project explicitly notes that function names, type layouts, and analysis notes outside of matched functions are inferences. This is a research-oriented project and is not intended as a playable port or a release of the game. Contributors must supply their own reference copies of the game disc and executable, as these are excluded from the repository. The project maintains a progress report and a function-by-function decompilation map to track source-marker coverage and byte matches. Further details on the working rules for the AI agents are documented in the project's repository at https://raw.githubusercontent.com/gunnaraas/rallytrophy/HEAD/README.md.
Reproduce it #
1. Extract the game files from the Rally Trophy ISO using 7-Zip. 2. Copy the official RallyTrophy.exe to the 'orig' directory. 3. Configure the required Visual C++ 6.0 SP5 toolchain. 4. Run 'python3 -I tools/match.py' to verify matches against the reference executable.
