# Gex 64: Enter the Gecko — matching Nintendo 64 decompilation

> This is a matching decompilation of Gex 64: Enter the Gecko for the Nintendo 64, USA release. The ROM is named gex64.z64 and must be big-endian Z64. make split extracts it, make build rebuilds it, and make diff must match the original before a change is submitted. Most of the game compiles without -mips3. Some files require -mips3.
