OpenTTD is an open source clone of the Microprose game "Transport Tycoon Deluxe", a popular game originally written by Chris Sawyer. It attempts to mimic the original game as closely as possible while extending it with new features.
This game is awesome! And they already made a port to the ds. And if we can get the mouse working nice with the arrows, it would be a cool game for the dingoo.
OpenTTD is opensource you only need the original graphics files from the orignal game.
