The Legend of Zelda: Ocarina of Time
- WARNING! -
The ROM this repository builds cannot be 'shifted', primarily due to some hardcoded pointers which have yet
to be dumped. Thus this repository is currently in an experimental and research phase and cannot yet be used
traditionally as a source code base for general changes.
This is a WIP decompilation of The Legend of Zelda: Ocarina of Time. The purpose of the project is to recreate a source code base for the game from scratch, using information found inside the game along with static and/or dynamic analysis. The only build currently supported is Master Quest (Debug), but other versions are planned to be supported.
It builds the following ROM:
- zelda_ocarina_mq_dbg.z64
md5: f0b7f35375f9cc8ca1b2d59d78e35405
Note: This repository does not include any of the assets necessary to build the ROM. A prior copy of the game is required to extract the needed assets.

Installation
Windows
For Windows 10, install WSL and a distribution by following this Windows Subsystem for Linux Installation Guide. We recommend using Debian or Ubuntu 18.04 Linux distributions.
For older versions of Windows, install a Linux VM or refer to Docker instructions.
macOS
For macOS, use homebrew to install the following dependencies:
- coreutils
- make
- python3
brew update
brew install coreutils make python3
You'll also need to build and install mips-linux-binutils.
Going forward in this guide, please use gmake whenever you encounter a make command.
The make that comes with MacOS behaves differently than GNU make and is incompatible with this project.
You should now be able to continue onto step 3.
Linux (Native or under WSL / VM)
1. Install build dependencies
The build process has the following package requirements:
- git
- build-essential
- binutils-mips-linux-gnu
- python3
Under Debian / Ubuntu (which we recommend using), you can install them with the following commands:
sudo apt-get update
sudo apt-get install git build-essential binutils-mips-linux-gnu python3
2. Download and set up qemu-irix (optional)
Note: We are currently testing a recompiled version of the compiler that does not require qemu-irix.
This step allows you to build with qemu-irix and the original compiler by adding ORIG_COMPILER=1 to the make command in step 6, for example if you experience issues with the recompiled version.
Download qemu-irix from the Releases section in the repository. Place it at a location of your choosing.
Open up your .bashrc file (~/.bashrc), scroll to the bottom, and add the following, replacing the paths as necessary:
export QEMU_IRIX="path/to/your/qemu-irix"
Save and close/reopen your terminal window.
3. Clone the repository
Clone https://github.com/zeldaret/oot.git where you wish to have the project, with a command such as:
git clone https://github.com/zeldaret/oot.git
4. Prepare a base ROM
Copy over your copy of the Master Quest (Debug) ROM inside the root of this new project directory. Rename the file to "baserom_original.z64" or "baserom_original.n64", depending on the original extension.
5. Setup the ROM and build process
Setup and extract everything from your ROM with the following command:
make setup
This will generate a new ROM called "baserom.z64" that will have the overdump removed and the header patched. It will also extract the individual assets from the ROM.
6. Build the ROM
Run make to build the ROM. Make sure your path to the project is not too long, otherwise this process may error.
make
If all goes well, a new ROM called "zelda_ocarina_mq_debug.z64" should be built and the following text should be printed:
zelda_ocarina_mq_dbg.z64: OK
If you instead see the following:
zelda_ocarina_mq_dbg.z64: FAILED
md5sum: WARNING: 1 computed checksum did NOT match
This means that the built ROM isn't the same as the base one, so something went wrong or some part of the code doesn't match.
Docker
1. Setup requirements
To use Docker, you'll need either Docker Desktop or Docker Toolbox installed and setup based on your system.
You'll also need to prepare a local version of the project with a copied base ROM (see Step 4 and 5 of the Linux instructions).
2. Create the docker image
From inside your local project, run the following command:
docker build . -t oot
3. Start the container
To start the container, you can mount your local filesystem into the docker container and run an interactive bash session.
docker run -it --rm --mount type=bind,source="$(pwd)",destination=/oot oot /bin/bash
4. Setup and Build the ROM
Once inside the container, you can follow Step 6 and 7 of the Linux instructions to setup and build the ROM, or run any other command you need.
Contributing
All contributions are welcome. This is a group effort, and even small contributions can make a difference. Some tasks also don't require much knowledge to get started.
Most discussions happen on our Discord Server, where you are welcome to ask if you need help getting started, or if you have any questions regarding this project and other decompilation projects.
