Hello! I got 2 arcade mashines from Midway. Terminator2 and Revolution X. Both of them have a really strange problem. When operated , all the guns shoot in the upper left corner. I try to calibrate them, and the machine said, that calibration is sucessfull, but when the game is on, the guns again shoot ONLY in the upper left corner. And the strangest thing is that BOTH arcades acts just the same!!!!! They tell me that calibration is sucesfull, but not work. So please, maby someone can help me with some advise or something. You are my last hope. Ill try to search some info high and low, but with no sucess. Thanks in advance!
