Here's an update of my progress:

  • 150 CPU Opcodes are now emulated. I've bug fixed quite a few existing ones, and corrected various errors.
  • 64x32 tilemaps now display correctly
  • Tilemap scrolling implemented
  • Automatic joypad reading implemented
  • SPU skipper implemented (Fakes the sound processor for now)

The result of all this is that a handful of new PD demos are working, and the following commericial ROMs are displaying some graphics:

Currently, these do not run any further due to unimplemented opcodes. Still, I'm on the right track...
