Since it's hard to find an official PAL SNES controller (which I want for its long cord) for sale, I got one of these and it's great. Maybe the best way to play Super Nintendo. I use it with the original PlayStation controller (the one with no analog sticks), plus a PlayStation controller extension cord. It's perfect and works fine with my SNES PowerPak.

Also works with my Logitech PlayStation 2 Cordless Action Controller.

[The first adapter I received was unresponsive unless I powered the SNES on and off enough times but Tomy sent a working replacement quickly.]
