Triforce%

Triforce% is a hybrid RTA/TAS "speedrun" of Ocarina of Time which uses Arbitrary Code Execution (ACE) to install a set of data loaders in system memory, enabling arbitrary assets (scenes, objects, music, etc.) in the game ROM to be seamlessly live-patched from the host PC. By modifying the game programming and assets, beta content cut from the final version of OoT is restored and brought to life on screen. A new plot is constructed based on this beta content and on urban legends from the late '90s, culminating in Link obtaining the Triforce.

But, in front of thousands of live viewers, once we have the power of the Goddesses--and the power to make the game whatever we can imagine--what will we use this power for?

Setup

• Install Linux (Ubuntu / other Debian derivative), either natively or through WSL/WSL2 if you're on Windows.
• Make sure you got the Git submodules. The build system checks for some of them but not all. You will need libpng-dev, libelf-dev, libglfw3-dev, and libglib2.0-dev for these to compile. You will also need build-essential in order to be able to compile anything for your local machine.
• In your python3, install pyserial (not serial), pillow, and psutil.
• Install the N64 toolchain from https://github.com/glankk/n64. See below for more detailed instructions.
• Get a copy of zzrtl which is stable enough to work on Linux with the default (i.e. non-Jared Johnson) scripts, e.g. 0.01r4. https://old.z64.me/tools/zzrtl/zzrtl-0.01-r4.zip Put this somewhere outside the Git repo (i.e. not in the toolchain folder).
• Copy local.mk.example to local.mk and edit the paths defined there to point to the relevant tools on your computer.
• Make a build-shortcut folder and paste the OoT 1.0U compressed ROM into it, with the name oot_1.0U_comp.z64.
• Make a build-romhack and paste the OoT 1.0U uncompressed ROM into it, with the name oot_1.0U_uncomp.z64.
• make. Do not use -j4 etc., some of the dependencies may not be correctly tracked/rebuilt in this case. Look for a Done building message at the end.
• If you make changes to Makefiles or any other part of the build toolchain, make sure to make clean.

N64 toolchain instructions

This was tried on a mostly fresh native install of Ubuntu 20.04, and on Ubuntu 20.04 through WSL2 on Windows 10. These are modifications/notes to the installation instructions on the glank N64 toolchain github page, so you should be following those instructions but also looking at this info at the same time.

• Install libgmp-dev.
• git clone the repo instead of downloading the zip file (because of the next step).
• When it says "navigate to n64-master", this means git checkout n64-ultra.
• Before ./configure, I did

sudo mkdir /opt/n64
sudo chown yourusername /opt/n64
sudo chgrp yourusername /opt/n64

• make -j4 or whatever works OK without issues.
• I don't think the make install-local-exec step is needed.
• If you don't already know, one way to add /opt/n64/bin to PATH is to add the line

export PATH=/opt/n64/bin:$PATH

to somewhere in ~/.bashrc, and then exit the current bash you are in and start a new bash session.

• To check that everything is installed correctly, run mips64-ultra-elf-gcc -v and verify that the output is a reasonable MIPS64 GCC version info.
