About emulators of some console (GBA, snes, SEGA) The N900 keyboard is perfect. But concerning Nintendo 64 and psOne you better have to buy a PS3 pad by the way!!! due to the 3D view in these consoles and due to the lack of joystick or touchscreen support, I think it's a bit hard to play with the keyboard! But you can still replace the joystick by the accelerometer!!!
