* 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
*** Channelwood Card 3385: Closing stairs upper door animation
* Playback at custom framerates - Needed for Myst Cabin Boiler videos.
* 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.

* 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.
* Myst's fortress rotation holo-simulator requires playing QT movies with edit lists backwards. For now this is hacked around in the Mechanical code so that the puzzle works properly.

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

=== Known issues ===
* Myst ME support is missing these codecs: QDesign Music 2 (partially working) and Sorenson Video 1.
* Myst ME 10th Anniversary Edition requires Sorenson Video 3 for the UbiSoft logo
* Myst 10th Edition requires the Myst ME codecs plus Sorenson Video 3.
** Since SVQ3 is quite large (and based on h.264), we may suggest the user just take the video from the Macintosh portion of the disc, which is QTRLE
* JPEG Optimization for Myst ME.
* The help system is missing in Myst ME
* Add "Drop Page".
* Add Transitions.
* Myst Demo Only - Add "Return To Main Menu"
* Myst ME Only - Add "Show Map" and Help System.
* Myst Original - Background sound restarts incorrectly compared to original interpreter on a number of cards. <br>Good test case for this is Myst Card 4697 and 4689 (Myst Imager Forechamber Tunnel - Background Music).<br>These play resource Ids 4697 and 4689 from VIEW sound block respectively, which is the same sound, but glitches <br>due to the playback restart. It is probable the original interpreter on new sound playback continues from the <br>same time offset, if this is within the new sound's duration i.e. thus no "seam" is heard.

Main Mohawk TODO

Video

  • 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).
  • Myst's fortress rotation holo-simulator requires playing QT movies with edit lists backwards. For now this is hacked around in the Mechanical code so that the puzzle works properly.

Myst Status

The game is completable to all four endings.

Known issues

  • Myst ME 10th Anniversary Edition requires Sorenson Video 3 for the UbiSoft logo
    • Since SVQ3 is quite large (and based on h.264), we may suggest the user just take the video from the Macintosh portion of the disc, which is QTRLE
  • The help system is missing in Myst ME

Riven TODO

The game first became completable with bb5db4a. As of 245b733, the game is completable with no prior knowledge.

Main TODO

  • Cleanup hotspot debugging mode. The water effect and videos write over it.

Living Books TODO

  • Take another look at how rewinding is meant to work.
