I found this adapter for the Nintendo DS (original) in a box of stuff I bought at an auction. I have no clue what it is or what it does, but I am curious. I was hoping maybe somebody here has either had one or knows what it is. The clear case it came in says Mad Catz, so I'm thinking its one of their products. I was unable to find anything similar on their website, so it's definitely an old, obsolete item. http://imageshack.us/photo/my-images/87/hni0030q.jpg http://imageshack.us/photo/my-images/838/hni0029x.jpg http://imageshack.us/photo/my-images/263/hni0028n.jpg Any help is appreciated.
