Hey guys,
Recently picked up a really clean Ultracade in a Dynamo Jamma+ cab, but of course the Ultracade PC was dead as a doornail. Decided to toss a Pandora's Box 4 in it, and after moving around some ground wires it works, and all the switches will work in test mode, but the button presses are really laggy, like you can tap 5 times before the switch fires on some buttons, and some work just fine. Any ideas what could be causing this issue? I tried a second PB4 and no change.
Thanks for any advice.
