Same here...and when you compare the values in that config file with the values listed in scancodes.txt, they do not match!
For example, it lists SELECT=30, 30 is NOT player 1 button...but player 1 button does, indeed, select. Back is listed as 48, but according to scancodes.txt, 48 does not equal the button that BACK is assigned to stock...so I am confused as all hell.
