There are a few linux-based NDS emulators already available, all using the mouse for touchscreen near as I can tell. The n810 would be pretty well suited for this if the screen were laid out portrait mode one screen over the other, and the hardware keys to the left used for controls. Ideally it would flip to landscape mode for games that used more hardware buttons than touchscreen interface...

Anyone heard of a DS emulator for the NIT platform?
