I didn't read all 4 pages of this topic, but when I first got my Arcade Card Pro I thought it was defective as well. Turned out to be my PCE converter. The seller was willing to take the card back and everything, but I cut a trace on the converter and suddenly it worked perfectly. That's a true story. I told the seller to f-off and that he could keep my money because I was keeping this damn Arcade Card Pro because it was awesome. Then I gave him a whole bunch of negative feedback for trying to take my awesome Arcade Card Pro away from me. I had eBay ban him as well. That part's not so true.
