## What was done

A GameCube static recompilation project builds a native PC version of Def Jam: Fight for NY from the user's own USA disc image, with new features including online multiplayer.

This project statically recompiles the GameCube version of Def Jam: Fight for NY into a native PC program. The repository describes a build that extracts the executable and game files from the user’s own USA GameCube ISO, recompiles the main program, and builds it with a PC runtime. No game data is included in the repository.

### Result and setup

The README describes a native PC build with new features such as online multiplayer. It documents using a plain USA disc image and building from source with the project’s installer and recompiler. The game’s content remains the user’s responsibility.

### AI contribution and limits

Public commit records include Claude Opus 5.5 co-author trailers on project work, including changes to the release instructions and repository preparation. The project’s own README does not give a detailed breakdown of which reverse-engineering tasks Claude handled, so this page records the co-authorship evidence without assigning Claude specific findings. The project is unofficial and requires a user-supplied copy.
