Mario Party (N64): Recompiled Mario Party (N64) into a native PC port with Claude

A developer released Mario Party: Recompiled, a native PC port of the N64 game Mario Party (USA) built through static recompilation with N64Recomp, N64ModernRuntime, and RT64, which translate the game's MIPS code into C. The project's author reports that almost all code, documentation, and tests were written by AI agents, specifically Claude Opus 5.5, under human direction and play-testing, with symbol names and addresses drawn from the mariopartyrd/marioparty decompilation. The port adds widescreen rendering, interpolated display rates, and multi-threaded process scheduling, ships no game assets or ROM data, and requires a 32 MiB big-endian .z64 ROM with SHA-1 1159bd56730094bfc71be30113e1cfc8bacf34f3 to build.

Evidence at a glance Loading source evidence… What was done Mario Party: Recompiled is a native PC port of the N64 game created via static recompilation. The project utilizes AI agents to write the majority of its code, documentation, and tests, while relying on the mariopartyrd/marioparty decompilation for symbol data. Mario Party: Recompiled is a native PC port of the N64 title Mario Party USA , achieved through static recompilation. The project uses N64Recomp, N64ModernRuntime, and RT64 to translate the game's MIPS code into C for native execution. The author reports that almost all code, documentation, and tests were written by AI agents, specifically Claude Opus 5.5, under human direction and play-testing. The project incorporates symbol names and addresses derived from the mariopartyrd/marioparty decompilation project. The port supports widescreen rendering, interpolated display rates, and multi-threaded process scheduling. It also provides a browser-based version built from the user-supplied ROM. The repository contains no game assets or ROM data. The author notes that this AI-written code is not offered to upstream projects, as they do not accept such contributions. Development and maintenance tasks, including widescreen adjustments for specific minigames like Piranha's Pursuit, are documented with co-author credits to Claude Opus 5.5. See the project README https://raw.githubusercontent.com/n64hub/mario-party-recomp/HEAD/README.md for build and usage instructions. Reproduce it Supply a 32 MiB big-endian .z64 ROM SHA-1 1159bd56730094bfc71be30113e1cfc8bacf34f3 at roms/marioparty.us.z64. Use CMake 3.31, Ninja, and the specified clang compilers to run the recompile and build scripts provided in the repository. Community Ask a question, share what worked, or follow the next milestone.
