I've got a mostly working terminator 2 game, but the player one gun doesn't track on the screen. It says it calibrates but still nothing. i swapped the plugs on the player 2 gun and it works fine as the player 2 gun. Is this a board issue? The guns don't operate on optical sensors but postion sensors (I had someone tell me it was a bad optical sensor). I notice the vibration dosn't work on either gun if that matters. Any ideas?
