Thank you for all your nice words. The reason for using a psx pad hack is that the psx interface is so popular that I can use it with PC and with my Dreamcast too thanx to adapters. I have two usb adapters for PC which work great, and other two adapters to plug psx pads into Dreamcast, which also work flawlessly. Ironically I do not have a psx or a ps2, but I also have the chance of using it with them. I think I could even plug it into a xbox, because I'm sure there must be PSX to Xbox adapters too. BTW, I printed the MAME logo reversed in a transparent sheet and used a cutter to cut it in wood (not thick wood). Then I sanded it and applied some filler to mend the little defects. I'm sorry I don't remember the model of psx pad hack. Any cheap pad will be ok to solder. Look for any of those models with transparent case. I got it for 5 euros. Mad Catz, High Frequency, etc make cheap psx pads.
