Help! I'm still looking for a schematic for this. The game is "running", but without controls. My I-40 controller adapter seems to not be getting power. I'm using a wiring harness from NBA Showtime, and I made proper connections to the I-40, but at the other end of wiring that connects to the PCB, one connector is wider (1 extra pin). Maybe this harness is not totally compatible with the Gretzky 3D hockey PCB??
