I made a stupid mistake I connect the j-pac board the wrong way and now button 2+3+4 don't work any more for both players.
Yes I'm an idiot, I just got it out of storage to put it my new place so was a bit too enthusiastic

Any help me out what I need to do to get it working again?
The monitor is also not working, would this also hurt that as well?
regards,
jippie
