Ya, I would prefer to use PayPal, but if I have to do check I suppose I will.
I was thinking of also trying to make my own adapter. I was looking at the pin outs on Mario bros and I realized it needs -5V, and the VS pin outs don't have that. Know any way to get the -5V to the Mario Bros Board?
You can use any old switching power supply to get the -5 with a Nintendo power adapter and make your own harness. Arcade shop has the adapter.
Another option too is to rewire the cabinet JAMMA and get a Nintendo to Jamma adapter.
