I just went out and bought SSBM(gamecube) + 3 gamecube controller. I get home to find that my younger brother lost the wiimote. Unfortunately, I can't figure out how to use a gamecube controller to navigate the main screen to start the disc. Any ideas? Is the wiimote essential?
Yes it is. You can use the classic controller but it needs to be plugged into the Wiimote. You will need to look for you Wiimote or shell out the cash for a new one.
