What was done #
A readable C++ reimplementation of Tony Hawk’s Underground 2 for PC, with tools for testing against the game and porting levels from related Tony Hawk titles.
This project builds a readable C++ reimplementation of Tony Hawk’s Underground 2 for PC, one function at a time, while testing against the running game. It includes a DLL and self-test tooling, Ghidra and Capstone workflows, and utilities for game data and script conversion. The README says no game files or binaries are included and asks users to provide their own copies.
Related level work
The workspace documents level conversion and porting from THPS3, THPS4, THUG and THAW, with game-specific input requirements and tools. The README describes the supported install layouts and the unwrapped executable needed for testing. A recent project commit reports that 15 zones from THP8 data load in game.
AI contribution and limits
A Claude Opus 5.5 co-authored commit is attached to the THP8 level-port work, including tests and integration changes. That is direct evidence of AI participating in implementation connected to the game reverse-engineering workflow. The repository’s build and test process loads game code in memory; the README warns that behavior-based antivirus may flag the self-test runner. Use requires legally obtained game copies and local build tools.
