Transport tycoon does have an open source engine. it was wrote by someone who is working on Scummvm. the stats look canny good so far!
Transport Tycoon Deluxe DOS requires a 25MHz or higher processor and at least 4Mb RAM running Windows 95. You must also have a SVGA monitor capable of 640x480 in 256 colours. Microsoft MS-DOS version 5 for the DOS version.
the open source versions called OpenTTD it required certain files from the game to run and works quit well. all someone needs to do is do a few hack to the source and we've got a Transport tycoon Deluxe on GP32. all be you need the game to play. The topic should be changed back and noted. i'm going to mess around and see what i can do to get it on the GP.
