Spintrak through a U-Hid USB.
Steam sees the board as generic, but offers config like a game pad. Even requires entries for items not present to save - or so it seems.
Searched and found nothing that applies. Steam help didn't seem to have a clear answer either.
Spintrak works with MAME without issue. Also has X-axis control of mouse - outside of MAME.
Any directional help would be appreciated.
