These classic games don't play well (or at all) using Nintendo's new-fangled motion-sensitive controllers. You either have to use the ugly Gamecube controllers or Nintendo's Classic Controller extension for the Wiimote. There are a few glaring problems with the Classic Controller. For one: it isn't very ergonomic at all, and two: it is wired and must be tethered to the Wiimote.
Nyko once again swoops in and saves the day with their Wing Wireless Classic Controller for Nintendo Wii. Not only is this controller more comfortable, but is completely wireless!
