## What it is
A work-in-progress from-scratch decompilation of The Legend of Zelda: Majora's Mask (N64 US 1.0), recreating readable C source code that builds a byte-identical ROM. It is a reverse-engineering research project, not a PC port, and requires an original copy of the game to extract assets.

## Use cases
- decompile Majora's Mask into readable C source
- build a matching Majora's Mask N64 ROM from source
- study how the original game engine was implemented
- contribute to a community reverse-engineering effort
- create mods once the codebase becomes shiftable
- analyze N64 game code for research or documentation

## When to choose
- you want to read or study reconstructed source code for Majora's Mask
- you need a byte-exact matching ROM built from source
- you want to contribute to the ZeldaRET decompilation effort
- you are researching N64-era game engine internals

## When to avoid
- you want a playable PC port of Majora's Mask
- you need a stable base for modding today, since the codebase can change drastically and some ROM sections are not yet shiftable
- you only have the MM3D version, which is a different game and unsupported
- you expect assets or assembly to be included - an original ROM is required
