News from BJA:
Quake2x Wiimote is a quick modification of Woogal's quake2x which adds support for the Nintendo Wii remote controller. The current version supports joystick and button input on all three controllers (i.e. wiimote, nunchuk, and classic controller). Unfortunately, ir-sensor input had to be disabled because it crashes on my gp2x. But it's impossible to use, so no one would probably use it anyway.
Quake2x Wiimote can be downloaded here.
Try it, its fun!
