Mario Party 4

About

Mario Party 4 is a 2002 party game by Hudson Soft for the GameCube, the first Mario Party entry on that console, featuring eight playable Mario-franchise characters competing across six boards plus a single-player campaign against AI opponents. Mario Party 4 is a work-in-progress decompilation targeting the GameCube original. Both USA ROM revisions build as fully matching, while most non-engine code remains undocumented and PAL/Japanese version work is currently stale. No game assets or assembly are included — a copy of the original disc is required to build.

Getting started

Building requires copying a supported GameCube disc image (ISO, RVZ, WIA, WBFS, CISO, NFS, GCZ, or TGC) of a matching version into the project's orig/ folder, then running the configure script followed by `ninja`; the disc image can be deleted after the first successful build. There is no working PC port yet, though one is in progress.

Known issues & limitations

• There is no working PC port yet; one is in the making.
• The project is a work in progress.

What you need to run it

Status & roadmap

• PAL and Japanese version support is currently stale, pending tooling that would make porting splits and symbols between versions easier.
