The Ocarina of Time/Majora's Mask Combo Randomizer
OoTMM is a randomizer for the N64 games Ocarina of Time and Majora's Mask. It combines both games into a single rom and randomizes the placement of most items in the games. A large number of settings are available to customize the experience.

You need the following roms:
- Ocarina of Time (U or J, 1.0)
- Majora's Mask (U only)
The roms need to be in their native byte-order (big endian). You can use programs such as Tool 64 to convert the roms to the correct format.
The roms need to be named oot.z64 and mm.z64 respectively and placed in the roms folder.
You can build OoTMM with either a DevContainer or your native environment.
You need:
- Docker
- Visual Studio Code
- Remote - Containers extension
Open the project in Visual Studio Code and click on the "Reopen in Container" button that appears in the bottom right corner. That's it.
You need:
- A C/C++ toolchain for your system
- CMake
- Ninja
- n64-ultra
- Node 22 or newer
- Git
On windows, we recommend using WSL2 to build OoTMM.
Install everything you need:
./setup.sh
You can generate a seed:
pnpm start:core:config
The output will be out/OoTMM.z64.
