# 2 Ship 2 Harkinian: a native Majora’s Mask port built on the decompilation

> Builds native Windows, Linux and macOS versions of The Legend of Zelda: Majora’s Mask from an adapted copy of the zeldaret/mm decompilation, with libultraship reimplementing N64 SDK functions. Game data comes from a user-supplied ROM and is packed into an archive that custom asset packs can override. It targets a playable PC port with enhancements, not a byte-identical ROM.

## Requirements & limits

- **Prerequisites:** No copyrighted assets are included: supply a supported copy of Majora’s Mask. The docs list SHA-1 hashes for NTSC-U 1.0 and NTSC-U GC versions. Built-in extraction turns the supplied game into an mm.o2r archive; custom .o2r or .otr packs go in a mods folder, and the README notes that fast64 does not fully support MM.
- **Prerequisites:** Source builds need the libultraship, OTRExporter and ZAPDTR submodules plus CMake. Windows uses Visual Studio 2022 with the v143 toolset, Python 3 and at least 8 GB of RAM; the Linux lists include GCC or Clang, Ninja, SDL2, libzip, spdlog, tinyxml2 and Opus/Vorbis libraries; macOS needs Xcode tools with SDL2, libpng, GLEW, Ninja, CMake, nlohmann-json and libzip.
- **Scope:** The reviewed develop commit follows release 5.0.1 (2026-08-25), published as Windows, Linux and macOS archives; nightly CI builds are for playtesting and may have bugs and crashes. The repository’s decomp_diff.py describes its game sources as changed decompilation code compared with the official zeldaret/mm repository. Rendering uses DirectX 11, OpenGL or Metal.
- **Testing evidence:** The README and build guide report no matching, checksum or fidelity checks for the port; the release notes list tweaks and bug fixes. Enhancement and randomizer code changes behavior relative to the original game.
- **License:** The repository is CC0 1.0, and the libultraship submodule is MIT; game content from the user’s copy keeps its own rights, and the README says the project does not condone piracy.
