I noticed that when I pressed a pedal on Gas Switch it mapped 2 controls.
Joy 2 Left Joy 2 Right
Sounds like you quickly pressed and released the pedal.
If you press and hold the pedal for a few seconds, it should only map one direction.
I am using an APAC. So I am thinking that maybe I have wired it incorrectly.
If the potentiometer center tab was wired wrong, you shouldn't get "Joy 2 Left" or "Joy 2 Right" mapped to an input.
- Check Windows Control Panel -- Devices and Printers -- right-click the game controller icon -- game controller settings -- properties to confirm that the pedal is working correctly.
Pretty sure that the only way your current setup could be mis-wired is if the axis moves in the opposite direction desired.
- If that is the case, swap the wires on potentiometer tabs 1 and 3 (5v and ground)
or you can reverse the axis in the MAME "Analog Controls" menu.
