Build Instructions

The RGBDS toolchain and GNU Make is required to build Cobalt from source.

make all

This will produce the ROM file in the bin/ subdirectory along with some additional debugging aids.

The Snake ROM is embedded into Cobalt by default, and the key mappings are like so,

GB	Chip-8
Right	0x9
Left	0x7
Up	0x5
Down	0x8

To change the ROM file and key mappings, you need to edit the src/rom.s file manually.
