This re-creation of the Super Famicom controller (that's the SNES to you, Euros and American Cowboy-Os) is what members of the Japan-only Club Nintendo are currently having shipped out to them, allowing them to play Wii Virtual Console games in old-school style. It's the exact same controller I used to use back in 1992 to garrote my little brother after a loss in Super Punchout!
Like the Wii's Classic Controller, this controller plugs into the bottom of the Wiimote, which allows it to establish a wireless connection to the console itself. Unlike the Classic Controller, though, it doesn't look absolutely hideous. Just make sure that none of the Virtual Console games you own require more than six buttons.
