If any PS3 users out there are interested, I recently found a simple way to use your PS3 controller on PC.
(There is another method out there but I could never get it to work.)All you do is download and install
this driver and when you want to use it, make sure the little program's window is open and that your Sixaxis (or Dualshock 3 which also works) is plugged in via usb. Naturally, the motion senstive feature won't work.
Currently I've only tried it with GTA: San Andreas on the PC and it worked fine.
