NES/SNES Controller/Audio Pmod

Thanks to @lawrie we now have NES running on the iCEBreaker. I think it would be really good to have a single Pmod that allows us to easily plug in NES Controllers and get Audio out of the iCEBreaker.

Main requirements:

  • 2 x NES controller connections
  • 1 Audio jack for audio out

Optional requirements:

  • Also compatible with SNES controllers
  • Additional inputs to select ROMs

What else would you like to see on here. Do you have a napkin schematic already of how you would wire this up?
