This page gives a summary of the engines supported by each Platform port.
Supported Engines by Platform
GP2X (*) : 640x480 or 640x400 games have visual and speed issues due to the need to scale to the GP2X 320x240 LCD.
GP32 (*) : The GP32 is limited to a maximum game data size of 128MB and does not have enough ram to support V7+ games.
PalmOS (*) : 640x480 or 640x400 games have visual and speed issues due to the need to scale to 480x320 or less. No issue with Zodiac Version. Not all games are supported.
Symbian OS (*) : 640x4xx games and Scumm V7 usually have issues due to memory constraints. Also some newer SVN game engines are built in, but not tested.
