## What it is
A complete community decompilation of Super Mario 64 covering the Japan, North America, Europe, Shindou, and iQue releases, written in C. It rebuilds byte-identical ROMs from a user-supplied base ROM, whose assets are extracted during the build.

## Use cases
- rebuild a byte-identical Super Mario 64 ROM from source
- study decompiled N64 MIPS assembly as readable C code
- create mods and ROM hacks of Super Mario 64
- port Super Mario 64 to other platforms
- learn reverse engineering of retro game consoles

## When to choose
- you own a Super Mario 64 ROM and want to compile a matching ROM from source
- you want readable C source for research, modding, or porting
- you want the canonical, most complete SM64 decompilation base

## When to avoid
- you don't have an original game ROM, since assets must be extracted from it
- you want a ready-to-play game rather than a source tree
- you need a Windows-native toolchain without WSL or Docker

## Facets
- artifact type: application
- maturity: active
- function: compiler, build-tool, reverse-engineering, game-engine
- domain: reverse-engineering, gaming-tools, programming-languages
- platform: windows, cli, cpp
- tags: decompilation, n64, super-mario-64, rom-hacking, mips, retro-gaming, game-development, linux, macos
