Looking for this Gamecube controller...

[Drev]

I remember seeing this site for this Gamecube controller that makes it easier to play Game Boy Player and the NES Zelda games. It's in the shape of the SNES controller, it has no analong stick or C-Stick, the directional pad is the same size as the snes one, but the A/B/X/Y buttons are placed in the style the Gamecube has. If you know the site, could you tell me? Thanks.
