Legend of Zelda: Majora's Mask (U) 1.0

This is a disassembly of Legend of Zelda: Majora's Mask (U) 1.0

It builds the following ROM:

• rom.z64 md5: 2a0a8acb61538235bc1094d297fb6556

Installation

Step 1:

If you're running Windows 10, install WSL. If you're running an older version of Windows, install a Linux VM. If you're already running a Linux OS, you're good to go.

Step 2:

Using sudo apt-get, install the following packages:

make
git
binutils-mips-linux-gnu
python3

Step 2:

Download build_tools.zip from the Releases section and extract it to the tools folder.

Step 3:

Open up your .bashrc file (~/.bashrc), scroll to the bottom, and add the following, replacing /path/to/qemu-mips with the location the qemu-mips you extracted from the build tools:

export QEMU_IRIX="/path/to/qemu-mips"
export MIPS_BINUTILS_PREFIX=mips-linux-gnu-

Save and close/reopen your terminal window.

Step 4:

Make a fork of the main repository https://github.com/Rozelette/Majora-Unmasked.git and clone your fork.

Step 5:

Navigate to the Majora-Unmasked folder you just cloned. Type the following commands:

git submodule update --init --recursive
pip install -r requirements.txt

Step 6:

You will need to acquire a copy of the ROM. The md5 of this ROM should be 2a0a8acb61538235bc1094d297fb6556.

Once this has been done, type, replacing <ROM> with the name of your ROM:

./tools/extract_baserom.py <ROM>

This will extract all the individual files in the ROM into a newly created baserom folder, as well as decompress the compressed files in a newly created decomp folder.

Next, type:

make disasm

This will create the build folders as well as a newly created asm folder containing the disassemblies of nearly all the files containing code.

Step 7:

Type the following:

make

If all goes well, a ROM rom.z64 should be built and the following text should be printed:

rom.z64: OK

If you instead see the following:

rom.z64: FAILED
md5sum: WARNING: 1 computed checksum did NOT match

This means that something is wrong with the ROM's contents. Either the baserom files are incorrect due to a bad ROM, or some piece of code is not matching.
