This mod is intended to give a couple of source-engine-like features to the Metroid Prime series. It requires my mod loader, a feature of Primehack.
If you don't have devkitPro installed and in your path already, then grab devkitPro's powerPC toolchain (Gamecube/Wii are the only toolkits needed)
https://github.com/devkitPro/installer/releases
Once installed, add (devkitPro install dir)/devkitPPC/bin and (devkitPro install dir)/devkitPPC/powerpc-eabi/bin to your path
Follow these instructions to install devkitPro, you should only need the gamecube-dev pacman group
https://devkitpro.org/wiki/devkitPro_pacman
Ensure it has been installed in /opt/devkitpro/devkitPPC, check to make sure that powerpc-eabi-g++, powerpc-eabi-ld, powerpc-eabi-ar, powerpc-eabi-as are all under /opt/devkitpro/devkitPPC/bin
Run make in the root directory of this project. This should generate an ELF under binary_dir/<game>/, and copy the mod metadata file (.mmd) in the same folder.
Grab Primehack version 1.0.4, start up your copy of Metroid Prime, and load the mod (it wants the .mmd).
Note: MP1 mod only supports MP1 GC NTSC v1.00, MP2 mod only supports MP2 GC NTSC.
