Main Mohawk TODO


  • Backwards playback/seeking
    • Myst ME:
      • Myst Card 4113: Retracting weight in the clock tower
    • Myst Original:
      • Stoneship Card 2138: Chest key animation with no chest present
      • Stoneship Card 2132: Chest valve animation when chest is empty
  • The Cyan logo repeats some frames at the end. I call it "Cyan logo syndrome." This is caused by the lack of handling of multiple edit lists. FFmpeg doesn't handle this yet either.
  • Some Cinepak frames have corruption.
    • The Myst linking book video on D'ni has a corrupted Cinepak frame (data-wise). Right now, we just skip that frame (and throw a warning). It looks like QuickTime does this too.
    • The CD (but not the DVD) version of Riven has at least two videos with a corrupt frame: the wood chipper (when power is directed elsewhere) and using the trap book before talking with Gehn (when not on Tay).
  • Unify the 8bpp to 16/32bpp code snippets. This is mostly done already. I have a patch to add it to graphics/conversion.h, but still waiting on that one.


The game is playable and should be completable to all four endings, though many issues still need to be fixed.


  • Myst ME support is missing these codecs: QDesign Music 2 (partially working) and Sorenson Video 1.
  • Myst 10th Edition requires the Myst ME codecs plus Sorenson Video 3.
  • JPEG Optimization for Myst ME.
  • Myst Original - Background sound restarts incorrectly compared to original interpreter on a number of cards.
    Good test case for this is Myst Card 4697 and 4689 (Myst Imager Forechamber Tunnel - Background Music).
    These play resource Ids 4697 and 4689 from VIEW sound block respectively, which is the same sound, but glitches
    due to the playback restart. It is probable the original interpreter on new sound playback continues from the
    same time offset, if this is within the new sound's duration i.e. thus no "seam" is heard.

Riven TODO


The game first became completable with r52735. As of r55299, the game is completable with no prior knowledge.


(In Order of Priority):

  • Finish External Commands (Many are done, most are self-explanatory)
  • Finish ambient sound handling: Only fading is left
  • Transitions
  • Possibly make looping MP2 sound faster; there's a slight click between iterations.
  • Cleanup hotspot debugging mode. The water effect and videos write over it.
