The Legend of Zelda: Ocarina of Time
- WARNING! -
This repository is a work in progress, and while it can be used to make certain changes, it's still
constantly evolving. If you use it for modding purposes in its current state, please be aware that
the codebase can drastically change at any time. Also note that some parts of the ROM may not be
'shiftable' yet, so modifying them could be difficult at this point.
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. It is not producing a PC port. For more information you can get in touch with the team on our Discord server.
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
We recommend using WSL on Windows, or native Linux, which the rest of this readme describes. We currently have instructions for
(These will also depend on the Linux instructions.) Some of these may also be out of date or unmaintained; usually our contributors use WSL, Linux, and macOS, so these instructions should be up to date.
Windows
For Windows 10 or 11, install WSL and a distribution by following this WSL Installation Guide. We recommend using Ubuntu 20.04 as the Linux distribution.
For older versions of Windows, install a Linux VM or refer to either Cygwin or Docker instructions.
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
- libpng-dev
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 libpng-dev
To install the Python dependencies simply run in a terminal:
python3 -m pip install colorama
If you are using GCC as the compiler for Ocarina of Time, you will also need:
- gcc-mips-linux-gnu
2. 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
This will copy the GitHub repository contents into a new folder in the current directory called oot. Change into this directory before doing anything else:
cd oot
3. 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", "baserom_original.n64" or "baserom_original.v64", depending on the original extension.
4. 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.
5. 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.
NOTE: to speed up the build, you can either:
- pass
-jNtomake setupandmake, where N is the number of threads to use in the build. The generally-accepted wisdom is to use the number of virtual cores your computer has. - pass
-jtomake setupandmake, to use as many threads as possible, but beware that this can use too much memory on lower-end systems.
Both of these have the disadvantage that the ordering of the terminal output is scrambled, so for debugging it is best to stick to one thread (i.e. not pass -j or -jN).
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.
