Debugger & Compiler
- Print & edit variables for cheating and for fun

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

Known Issues and TODOs

Render issues:

- WME3D: rendering does not support screen size change [Bug #12630]
- WME3D: rendering does not support overlays [Bug #12631]

- WME: Engine doesn't use correct screenmode [Bug #11160]
Performance issues:
- WME: 5MA - wasps animation is too slow [Bug #6649]
- Theora player issues [Bug #6500]
Font issues:
- Last letter of text lines is missing sometimes. Notable case: 1 1/2 Ritter - Menu font problem [Bug #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 ;).

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]
WME: Add save thumbnails to Corrosion [Bug #11032]

Known Issues for specific 2D games

Known Issues for 5MA

Known Issues for Carol Reed 4 - East Side Story

Known Issues for FoxTail

selection arrow in dialogues menus seems to be drawn a pixel off comparing to original game (need more testing with different FoxTail versions)
text in books contains extra '^' character at the beginning of some paragraphs (incorrect split? some kind of specially added control character?)
saveload progress bar is not drawn under overlay (I need to learn how to deal with dirtyrects to fix this)
savegame description encoding seems to be wrong for some reason for Russian (may be caused by changing encoding during the game)
OpenGL render does not support dynamic lighting: `WARNING: BaseSurfaceOpenGL3D::getPixel not yet implemented!`

File() method should return hardcoded values for "while", "true", and "pDevice" values

	var file = new File("while");
	file.OpenAsText(1);
	var code = file.ReadLine();
	file.Close();
	if((code != "EAA34D79-55CE-4d4f-8DFA-A7B733713DB7")) {

	file.OpenAsText(1);
	var code = file.ReadLine();
	file.Close();
	if((code != "9B EB FB 94 84 8E C7 3C 94 AA 0E E2 59 AF B6 D7 30 1D DB 5B 1A 49 2d C7 A7 2C 5C FB 3C 96 75 4f 75 99 4A 2E C8 06 9A 4a BB 77 EA 04 E7 30 59 F3")) {

}

File() method should lookup other files at /txt/ folder inside DCP package, not at the package root
