About

A work-in-progress decompilation of Gex 64: Enter the Gecko.

Getting started

Needs your own legal USA ROM in big-endian z64 format, placed in the repository root and renamed as the setup describes. Setup can be done in a Docker container or locally with Python and MIPS binutils. Then clean, split the ROM into assembly and binary pieces, build, and run the diff step, which must show a match before a pull request.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game.
