Pedals are widely used in racing games along with steering wheels. If you already have such a foot control device and want to use it in other unsupported games, eg, as an extra 1-2 "buttons", is it not possible to use software like Girder / EventGhost, etc, or whatever came with the pedal to get the pedal to mimic a keystroke of 1-2 typically unused keys (say "J/K"), in the same way xpadder can act like a 'controller to keyb + mouse simulator', and then map the mimicked key in the game itself as a regular key bind?
