/vr/ - Retro Games

I picked up a model 1 TMSS High Definition Graphics Genesis. The console works fine except for the fact that it always reads an "up" input on the first controller d-pad, even when a controller is not attached. Occasionally it will work okay if a controller is connected for about ten seconds before resuming the up input. I tried reflowing the solder joints directly attached to the controller port and continuity tests show that there is at least a line between the pins and the first set of solder joints. I think the issue is related to pin 7, but I'm not very knowledgeable about this system. Would replacing the controller port be a possible fix? Also, does anyone know what EM18 connects to on pic related?
