Where does the ground go on jamma? The ground at pins 1/2 (power supply end) are dead on jpac. So if your other inputs are using the ground at other end (by buttons) then then theres your answer
Oh I remember you. You didn't want to buy a Mame from me cause my prices were too high.....
My machines are warrantied for a year![]()
Which ps2 port are you using on the jpac. Use the one that says PC above it
Im pretty sure that light stays on. I'll check tonight when I get home
Just to clarify;
The machine worked before transport?
Did you unplug or disassemble anything for transport?
Try sending/programming your button configuration to the JPAC again using the WinIPAC program. It also has a test menu you can bring up to see what button inputs are registering properly. I've had a few instances where it's programming got confused/corrupted and that did the trick.
Are the switches actually clicking when pressed? Have you jumped a ground from a working switch to the problem switches to see if it's a bad switch/bad ground.
Do you have a multimeter to check continuity from all grounds?
