How exactly is the wheel calibrated when what it is pointing to on the playfield doesn't match with what it reads on the DMD in test mode? In the manual, it says to rotate it in the opposite direction one full revolution when you move the wheel manually. I do that, exit the test, then re-enter test. It then lands on another item that still doesn't match, maybe closer than before, maybe not. I had it match once, exited, then re-tested and it was wrong again. Seems just random. Since this game is on 1.2, I'll update to 1.3 and see how that goes.

First, the decal has a notch that lines up with the notch on the wheel. After the decal is on correctly, the way the game figures out what lines up is there are two opto switches, one opto switch activates only one time per revolution, the other activates at each space on the wheel. The wheel spins, and when the game sees the first opto it knows where that is on the wheel, then it uses the other opto to count how many spaces from there it is. Once it knows how many spaces from the reference point it caculates what award "should" be awarded. Not the most reliable system, but works mostly.

So it either knows where it is, or it needs to be cleaned or is faulty. No setting it to a zero point or other recalibration function. Got it.

Edit: this issue was fixed by replacing the $25 wheel opto board.
