Here is a novel way of playing games on my Nokia N900. Emeryth of EmerytHacks has created himself a gamepad that connects via the USB port. The gamepad fits on top of the keyboard. It has 8 buttons and a PSP joystick and emulates a USB keyboard. It will work with all games and programs. Take a look at the video and visit his website for photos and more information. It’s genius.
The big question is when will this be on the market? Perhaps you can put that to Emeryth.
