chip8 emulator

Chippy

Chippy is a chip8 emulator written in rust, which I hacked out in a few days. It should be able to run most ROMs without issue.

Missing

• The delay timer and sound timer are not fully implemented.
• keypad input is currently hacky and may not work fully.
• Timing logic is hacky.
• The following instructions are unimplemented:
  • 0xF_29 set I = location of sprite for digit r[_]
  • 0xF_33 store BCD of r[_] in I[0..2]
• Super Chip-48 instructions are not supported.
