Yo, stop while your ahead man! Save that 50 dollar pcb for making yourself an arcade stick as this will definatelly not, I repeat not work. Maybe I am wrong, I've been known to be wrong a couple times in my life! But I don't think so.... I recently made, with an xbox street fighter anniversary pad, I repeat the pad, not the stick version (easy for hacks), an arcade stick with sanwa rg buttons, a sanwa jlf-8yt joystick, and two rare led sanwa buttons (one the shape of a star, the other a heart-used a two hacked usb cords to supply power to the bulbs), for my 5 yr. old daughter for Christmas. I think it is impossible due to needing microswitches to send the current to the copper source on the specific pad in question. The plastic buttons on the 360/ps3 are in totally different positions, and although you may be able to desolder the analog directs and realign them, I doubt one could move the copper traces on the pcb itself to align directly under the other system in questions buttons. Unless they make microswitches smaller than arcade ones, which I have never seen in a hacked pad... It's a great idea, but doubt it is possible. On a brighter note, that black strip on one side of the double sided ps3 pcb, looks as though it might be able to be used as a solderless hack. If indeed that black strip thingee has all the directions/button copper runs running to it.
