I've ported Quake 1 to the Nintendo DS. Though playable but yet not finished it currently runs between 20 and 30 fps when finished up to a possible 50+ fps. Now that the DS's has homebrew WiFi
drivers it will also be possible to play the game online. The port of Quake still needs a lot of work but I do not have much time to work on it anymore. So I'm looking for some help to finish it the port. There is a video
along with more information.
