Mohawk/TODO

Main Mohawk TODO

Video

• The QuickTime parser is basically complete.
• SEEKING!
• 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.
  • This would require seeking, so that needs to be implemented first.
• 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 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.

Myst TODO

The game is not currently completable for many many many reasons, but support is definitely increasing steadily. The ages are currently at least partially explorable.

Main TODO

(In Order of Priority):

• Hotspots/Resources
  • Type 10, 11 and 12 support required to implement slider functionality.
  • Opcodes
• Video seeking (see above)
• Myst ME support is missing these codecs : QDesign Music 2 and Sorenson Video 1.
• Myst 10th Edition requires the Myst ME codecs plus Sorenson Video 3.
• Loads of cleanup

Riven TODO

The game is currently not completable because of these missing parts (there are more puzzles after this missing, but these are the big ones in the way now):

• bspit, gspit, jspit, pspit, tspit: Cannot complete slider puzzle on domes.
  • See *_opencard, *_resetsliders, *_slidermd, *_slidermw

Main TODO

(In Order of Priority):

• Card Changing Video Problem
  • Some hotspots do some hackery where they load a video, change to another card, and then play that video. However, we currently clear the list of loaded videos when changing cards; this stops videos from playing afterwards.
  • Affects the Rebel Tunnel puzzle stones
  • Affects the cage on ospit
• Finish External Commands (A few are done, most are self-explanatory)
  • Some require video seeking, see above
• Fix Memory Leaks; The memory consumption of the game goes up ~200 kilobytes per card. Not good! The hotspots are not freed when changing cards. Freeing them can (and will) segfault the game.
  • Actually, I'm not sure if this happens anymore. Need to check...
• Make looping MP2 sound faster; there's too much of a pause between iterations.
• Cleanup SLST handling
  • Fading not handled
  • Some sounds do not play (maglev from tspit to jspit), is this right?
• Transitions
• Cleanup hotspot debugging mode. The water effect writes over it.

Stack TODO/Known Bugs

May be caused by missing features!

aspit

• Numbers are missing from Catherine's journal.

bspit

• xbchangeboiler and xbupdateboiler need to be completed.
• Videos need to be added to the water flow controls (hardcoded).
• The Ytram trap only partially works currently. xbsettrap, xbcheckcatch, and xbfreeytram need to be implemented.

gspit

• The map viewer is not implemented, but you are still able to choose an island.

jspit

• Videos need to be added to the elevator (hardcoded).
• Ambient sounds don't work when clicking on a stone in the rebel tunnel puzzle.
• The video for opening the right bamboo door from the destroyed forest doesn't work; we need to update videos when in the delay script opcode.

ospit

• Overall, in decent shape. The non-Gehn related puzzles are completable.

pspit

• Everything acts the way it's supposed to. I have seen no gameplay bugs so far, other than the missing external commands.

rspit

• Everything acts the way it's supposed to. I have seen no gameplay bugs so far, other than the missing external commands.

tspit

• Need to finish the marble puzzle. It is currently bypassed. xt7500_checkmarbles, xt7600_setupmarbles, xt7800_setup, xdrawmarbles, and xtakeit need to be completed.

Other Games TODO

• They (mostly) all use QuickTime video, but there are some weird codecs. My QuickTime player (the latest version!) can't handle the Zoombini video codec. It says it's CDToons. The FourCC is 'QkBk'. I have no idea what that is. The sound codec is raw sound though. Some still use Cinepak (like "The Chief" videos).
  • The re-release of Zoombinis uses Bink Video!
• CSAmtrak/CSWorld use .FON resources for fonts. They're basically .FNT files in an NE library.
• Zoombini uses a TrueType Font.
• The RLE compression methods are required for the older Living Books games. Only RLE8 and LZ have been observed in later Living Books games.
  • This actually might not be RLE, it doesn't look like that compression...
