Known Issues and TODOs

  • Render issues:
    • PSP: Pixel Format RGBA8888@4 is not supported [Bug #12585]

    • Last letter of text lines is missing sometimes. Notable case: 1 1/2 Ritter - Menu font problem [Bug #11007]
    • RTL does not seem to always work for Persian games

Legacy TODO List

Not sure if this is already fixed or not. Need to look at this later.

  • Optimize UITiledImage
  • Use more than one dirty rect
  • Font-sizes are wrong enough to allow Dirty Split to draw text that is hidden in the original game (most visible on the coin-interface)
  • Alpha-masks for Theora-videos are broken on big-endian platforms

Bugs Also in the Original

In the following you will find a number of bugs which actually already occur when using the original interpreter / .EXE. That is, those errors are bugs in the games themselves, not in ScummVM. Still, we sometimes are able to implement workarounds, meaning ScummVM at times works better than the original ;).

Note that neither of these lists is complete.

Not Fixed

  • WME: Dirty Split - Dialog coming out of wrong character [Bug #6203]
  • WME: Some games are using same fonts for selected and normal text [Bug #11287]
  • WME: The Kite - Overlapping bug [Bug #6721]

Fixed

  • WME: 1 1/2 Ritter - Graphical slider issues in sound options menu [Bug #6567]
  • WME: Bickadoodle - Assertion on climbing the mountain [Bug #6594]
  • WME: Rosemary - Sprite flaw on going upwards [Bug #6572]
