Ok, we just about all know that you can modify your snes controllers to work on your nes. But doing that makes your controllers unplayable on the snes. But I have solved this problem with my s2nes adapter. I had a controller port from my retro duo that I would not be using in my portable, so I decided to make use of it. Also, I mainly did this because I don't have any nes controllers. So anyway, I used a sega genesis power adapter shell for the case (ironic, aint it?), and I bought an nes controller cord from Tibia (thanks, Tib!) Anyway, enough words, moar pics!

An above view of the whole thing.

SEGA!!!
Oh, and BTW, yes that is electricians tape around hot glue on the nes controller plug.
Oh, and I forgot to mention. I will be entering this in Kurt's controller contest, if its allowed. I don't see why not though, as it is an adapter for controllers.
