Released alongside the Wii on November 19, 2006, the Wii Classic Controller is a great alternative to the Wii Remote for Virtual Console games, however, it has some compatibility with regular Wii games, like Mario Kart Wii.

It features 2 analog sticks, a digital d-pad, 7 digital face buttons, 2 digital shoulder buttons, and 2 analog shoulder buttons. The controller connects through the extension plug in the Wii Remote, just like a Nunchuk.

The model number is "RVL-005." "RVL", found on all official Wii products, references the Wii's development codename "Revolution."

I found this Classic Controller at a thrift store for a few dollars, which is a pretty good deal, however it is kind of dirty, so I'm going to disassemble it in order to clean it.
