I just rebuilt my controllers with parts from Best Electronics. I now have 3 perfect controllers! But I have a problem with the system.
For any controller in the 1 player port (this is a 2-port system) the front button (the one that allows you to jump in Moon Patrol) doesn't work. All the other buttons, including the keypad, the start, pause, reset, and back buttons, work.
Take that same controller, place it in controller port 2 and it works perfectly.
Why does that one button not work in port 1?
More importantly how can I fix this?
