Even if it works with Cursor, it'll be difficult to play the game. Axis more accurately reflects how a PC FPS receives mouse input (i.e. it only tracks changes when you move). Cursor is more difficult to control since your mouse and mouse pad will act like a big C-Stick, and you constantly need to recenter your mouse just to stop looking in any direction.
OP - Do any of the other buttons work? More importantly, does the little dot inside the circle (in the GCPad config screen) move at all when you move your mouse?
