Hello! I picked up a Flashback 4 today, but it only came with the P2 controller. I was just wondering if it were possible to convert the P2 controller to be used as P1? I have a couple extra small buttons I could solder on the board, to add the 3 external buttons on the p1, if need be. I'd just like to get some fun out of the little system. I'm almost certain that this is probably covered a dozen times over in this forum somewhere, I just haven't had much luck sifting through the tombs of knowledge contained here.
