hey everyone. i have a 2100 in 1 jamma that i have a black button hooked up to use as the coin button. The jamma starts up get a title screen with the games listed but buttons and joysticks dont move or operate a function. i can push setup on the separate board and it opens on screen but also needs a button push to do anything. Any ideas the people i bought it off just keep telling me the same things to do even after i send the pictures showing i have done that. so close to playing just need a reason why it wont go past that title screen. Thanks in advance
