Wireless NES gamepad

I will try to fit a PS3 game controller into at a NES gamepad! So I can relive the 80's from the comfort of my sofa, 5 meters away from my 50" flat screen.

I'm starting with a regular old NES gamepad which I bought from Tradera (swedish ebay)

Using paint, I'm trying to figure out how the wiring is done. This will probably help me merging the game controls later.

Now, let's open the wireless PS3 controller!
