Charlie and SINT try to use 320x200 with 16 bit color, WORMS 640x480.
You could try 32 bit or 24 bit color or a higher resolution for
Charlie and SINT. Charlie and SINT also seem to work at 640x480
and 800x600 with 32 bit color on my computer (but the startup
screen doesn't look good).
You can do this by changing the arguments for startGame. For
example in the Start function in Charlie.icl:
= startGame DuckGame initialGameState [ScreenSize {w = 640, h =
480}, ColorDepth 32] world
