That is very cool... I'm looking forward to seeing it, and yes I'm 
currently using the SDL component. I switched the game over a couple of 
months ago.

What I did to relieve the problem for now was to call the WAIT statement 
a bunch of times using a FOR...NEXT loop. That way even if my frame rate 
is low, the gamepad's READ event is allowed to trigger multiple times 
per frame.
