If you want to browse the stage setup files, use this table to find the filename:

Stage	File
Defection	setupame.c
Investigation	setupear.c
Extraction	setupark.c
Villa	setupeld.c
Chicago	setuppete.c
G5 Building	setupdepo.c
Infiltration	setuplue.c
Rescue	setuplip.c

There is also a stagetable.txt in the repository root which includes multiplayer stages.

Installation Requirements

• make
• mips build tools (Debian/Ubuntu: binutils-mips-linux-gnu, Arch: mips64-elf-binutils from AUR)
• Python 3

Extracting the base ROM

Before you do anything you need an existing ROM to extract assets from.

1. Save your existing ROM file into the root of the repository with the name pd.ntsc-final.z64. It should not be byteswapped (the first four bytes should be 0x80371240).
2. Run make extract. This will create an extracted/ntsc-final directory containing assets from your ROM.

Compiling

The project can do the following:

• Build individual ucode binaries (boot, library, setup, rarezip and game) which match the ones extracted from the base ROM.
• Build a functioning ROM by splicing your stage setup and lang files into an existing ROM.

The project does NOT build a full ROM using the C code yet.

• Run make to build the individual ucode binaries. These files will be written to build/ntsc-final.
• Run make rom to build a ROM from the stage setup and lang files. The ROM will be written to build/ntsc-final/pd.z64.

How do I know the built files are matching?

Run make followed by make test. If make test produces no output then everything is matching.
