RetroZone to the rescue. For $19 you can buy from them
an adapter that plugs into the Wii’s GameCube port
(although the image above looks pretty clearly to feature a USB plug) and lets you connect one of those super hip NES or SNES controllers. Yes, we know the Wii’s Classic Controller only costs $20, but it’s hardly the same. The NES adapter goes on sale in January, with the SNES adapter following later in the quarter.
