Use a Nintendo SNES controller on a Sony PSP!

Some time ago I was contacted by a nice guy in the US. He asked me wether I would be interested in building a psp mod for his partner. She has limited use of one of her hands and as such cant use a psp, but she can however use a SNES controller perfectly (I’ve seen it, its quite a talent). So he asked if I would be able to add a SNES controller to a PSP for her. Well at long last here it is.
