Changing Individual Rom Settings Help

[heinekenlvr]

Hi,
OK I have Atomic FE up and running with my keyboard acting as the controller. I have a Pole Position steering wheel, gas pedal and shifter which I want to use instead of the keyboard. I have the steering wheel connected to an I-Pac and the gas pedal connected to an A-Pac. Outside of the games the computer see these and they work perfectly. The only two ROMS that I want to run are Pole Position I and II. I know that when the game starts that if I hit the TAB key, I enter the game settings page but this where my knowledge ends. How do I change the game settings to use the steering wheel, gas pedal and shifter? Is there a link to all of the mame game setting commands? Thanks.
