About

A static recompilation of MOTHER 3 (Game Boy Advance) to native PC, built on the gbarecomp framework and forked from EmeraldRecomp. The ROM's ARM7TDMI machine code is statically translated to C, and the runtime models the PPU, APU, DMA, timers and save chip. Any code path the recompiler missed runs through a built-in interpreter and is cached per ROM.

How it differs from the original

Its stated goals are a low-latency native build, widescreen presentation, and a moddable game through function-level hooks.

Getting started

You must supply your own legally dumped ROM and BIOS; the runtime refuses to launch on an unrecognized ROM. There are two targets, a Japan ROM build and an English fan patch build. Build from source with MSYS2 mingw64, CMake, Ninja and SDL2. Keyboard and controller bindings are in keybinds.ini, and Shift+F1-F9 saves to a slot while F1-F9 loads it.

Known issues & limitations

The runtime refuses to launch with an unrecognized ROM.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game (Game Boy Advance version).

You must supply your own BIOS.

Features

The project aims for widescreen presentation and modding through function-level hooks.

Controls

Licensing & legal

Additional notes

Audio latency: Audio latency can be tuned with environment variables, and raising the target buffer is suggested if audio crackles.
Decomp symbols: Only symbol metadata from the Kurausukun/mother3 decompilation enters the build.
