* Debugger & Compiler
** Print & edit variables for cheating and for fun
** Warp to scenes to reproduce some game-specific bugs faster
* Implement script patches (like in SCI) for fixing original bugs (like, 1 1/2 Ritter slider) and accessing interesting dead code (like, debug screens and level editors bundled inside game packages)
 
=== Features required for a few games only ===
* Non-English input is not supported

=== Known Issues and TODOs ===
* Render issues:
** PSP: Pixel Format RGBA8888@4 is not supported {{Tracker|id=12585}}
** WME3D: rendering does not support screen size change {{Tracker|id=12630}}
** WME3D: rendering does not support overlays {{Tracker|id=12631}}
** Dirty rects are working wrong sometimes. Notable case: Helga Deep in Trouble - Graphic mistake {{Tracker|id=9683}}
** WME: Engine doesn't use correct screenmode {{Tracker|id=11160}}
* Performance issues:
** WME: 5MA - wasps animation is too slow  {{Tracker|id=6649}}
** Theora player issues {{Tracker|id=6500}}
* Font issues:
** Last letter of text lines is missing sometimes. Notable case: 1 1/2 Ritter - Menu font problem {{Tracker|id=11007}}
** Some persian fonts seems to be a bit cropped
 
=== 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 ;).
