About
Harvest Moon 64 Decomp is a full decompilation of the North American and Japanese Harvest Moon 64 ROMs, recovering all game functions, data, and the game's custom cutscene and dialogue bytecode as matching, buildable source code. It includes tooling to extract sprites, animations, maps, text, and audio, and a build system that supports modding through dedicated development branches.
Getting started
Building it requires a MIPS toolchain, set up either through WSL2 or a provided Docker workflow, plus your own legally obtained Harvest Moon 64 ROM placed in the project directory before running the provided build commands.
Additional notes
- Modding
- The build system supports what the project calls 'shiftability' for modding — letting the linker relocate memory addresses freely once a couple of matching-only build files are removed — and recommends using the dedicated dev branches as a modding starting point.
