A gameboy emulator meant to run on N64 hardware.
To build, you will need to locate the original gameboy's boot rom and save it to a file named data/dmg_boot.bin. As well as data/cgb_bios.bin for the gameboy colors.
You should be able to find both of these files here
https://gbdev.gg8.se/files/roms/bootroms/
You will also need to supply the gameboy rom you want to build into an N64 rom. You should put the gameboy rom into the data folder
and update the include path in spec under the gbrom section
