A/B board question...

I know its a bit off topic (being capcom) but I'm thinking of picking up some cpsII games for my supergun, which is now working great thanks to the help of people here.

There is an extra cable that is not used on the MVS board which I assume is for the other buttons. The thing is, from the pictures I've seen of A/B boards the connection jack on the B board is three times the size of the free one hanging off the supernova. What gives? Due I need to cut the wires and splice them into the bigger jack on the CPS2 board? Is there an adapter that I'm missing? Do the CPS3 boards use a different jack? gah
Thanks

What you need is the other wiring harness which is specific to the CPS2 hardware that is often called the kich harness which plugs into the A-board in the jamma plus connector.

Thanks!!!

I'll see about getting one. more fight game goodness on the way
