Cobalt is a Chip-8 interpreter written in assembly for the Game Boy.
The RGBDS toolchain and GNU Make is required to build Cobalt from source.
make allThis will produce the ROM file in the bin/ subdirectory along with some additional
debugging aids.

| 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.
The Makefile is adapted from the GB Boilerplate repository, which is under the MIT license. A copy of the license may be found in the README/ subdirectory.
