What I did was this, I jacked one of my old Genesis controllers, cut off the end that plugs in, and connected all the wires to the plugs on the dualshock controller. It was hit and miss until I finally got the wires plugged in the right combination. I set it up as a serial mous for windows (so needless to say, it's functionality is cut some). I wouldn't reccomend this at all (I got bored), it's not very pleasant. Of course, the shock doesn't work, but I'm amazed it worked in the first place.
