Known Issues:

  • General Emulator Functionality Gaps
    • "Magical" MPEG is not completely understood and is not emulated the way the original hardware does this
      • Issue: #2
    • Video overlay is not implemented properly resulting in either an non-ideal VGA picture or non-ideal MPEG picture.
      • Should use proper SDL functions for this. Will address when rebase to DOSBox SVN trunk.

    • DMA streaming is not emulated
  • Return to Zork

    • Possible audio issues; clicks/pops
      • Bobbytoz consistently reports this, I have not (yet) reproduced
