I want to use an SNES controller with my DS Lite...

[hackanub]

So, I'm looking for pinouts for the SNES controller, but I can't find any. I already have a pinout for the DS Lite, so that's not a problem. Can anybody point me in the direction of some pinouts for the SNES controller? I would be extremely grateful.

Basically, I want to do this mod: http://pbowab.blogspot.com/2009/02/my-nintendo-ds-nes-mod.html except switch out the NES controller for an SNES controller.
