I had trouble with the US KOC where key 5 wasn't registering at all when I played 2P. I switched to 1P and it was working. When I opened and tested the controller, it seems that there was a cut in one of the traces. I couldn't find that cut but I soldered a wire from key 5 to the 2P side connector. Works like a charm. I'm weary of the quality of the US KOC. |
