Cowgod's Chip-8 Technical Reference

• chip-8

  1 273 10.0 Roff

  A collection of CHIP-8 programs and documentation (by mattmikolay)

For anyone looking to write a CHIP-8 emulator, Matt Mikolay's writeup is less ambiguous:

If you want to target the original Cosmac VIP behavior, corax89's test ROM is good:

• chip8-ce

  1 2 10.0 C

  CHIP-8 Emulator written in (e)z80 assembly and C for the TI-84+ CE

I used this reference to write a CHIP-8 emulator in Z80 assembly a couple years back: https://github.com/mnurzia/chip8-ce

• chip8-test-suite

  15 271 7.3 Roff

  A collection of ROM images with tests that will aid you in developing your own CHIP-8, SUPER-CHIP or XO-CHIP interpreter (or "emulator")

I can recommend Timendus test suite (which includes the one mentioned as well), as a more thorough set of tests and verification utilities: https://github.com/Timendus/chip8-test-suite

There are a lot of other useful references and tools worth mentioning, depending on how much hand-holding you want when implementing the emulator:

• viper

  1 19 10.0

  Scans of the VIPER newsletter (by mattmikolay)

The VIPER newsletter for RCA VIP owners has quite a bit of the early CHIP-8 lore: https://github.com/mattmikolay/viper/ -- I wrote the "CHIP-8 Assember in BASIC" in Volume 6 issue 1.

• emu8

  1 0 0.0 Python

  Naive Chip-8 interpreter written in Python (by dreary-dugong)

I just used this reference to make my chip-8 python interpreter a few months back. As others have said, there are some ambiguities that caused a few headaches for me. Add to that some broken roms, and the process ended up a lot harder than it needed to be.
