I have a model 2 Sega Saturn, but, it's a weird one, the power supply unit isn't attachd to the top caseing, and the game pad connector is a seperate unit from the mainboard, from taking the system apart multiple times for various modifications (swap, 50 60, repairs) I have snapped the wire, it is now being held in place by a peice of metal, so only the first control pad works (it also, for some reason, stops my light gun from working in either port, but all the buttons in my saturn pad work). Help
