The following additions/modifications were made to the core emulation code:

  • Support for ColecoVision MegaCart(R)
  • "The Heist" now works correctly (memory initialization bug).
  • Added support for Opcode memory expansion.
  • Added support for "Lord of the Dungeon" (original 32k or trimmed 24k).
  • Mode 2 masking now works correctly (supports Daniel Bienvenu games).
  • Mode 0 and Mode 3 now work correctly ("Cabbage Patch Kids Picture Show" and "Smurf: Paint 'n Play Workshop" now work correctly).
  • Fixed graphic corruption that would occur when switching between games (VRAM and related state were not being reset correctly).
  • Fixed save/load state bug where the emulator would incorrectly report that the save was invalid (memory was not being cleared correctly).
  • Fixed save/load state bug causing the palette to not be restored correctly (Aquattack, War Room)
  • Fixed issue where noise channel wasn't starting when it should (Matt Patrol).
