How?

I have 2 Wii remotes. A white one and a Black one. How Do I change which one is the first player? I want to change the Black one to first player.

I know. But when I try and turn it on with my Black remote it doesn't turn on. Only the white one turns on the wii.

You'll have to sync the wiimote to the system. Turn on the console using the power button on the unit. Open the front flap and press the red sync button. Open the battery compartment on the Wiimote and press the red sync button there as well. Once synced, you should be able to use your new controller just like the original.

You can also go into the Wii Menu, click controller settings, and select reconnect Wiimote. Press the 1 and 2 button on Wiimote in the desired order of the controller, and it should sync with the console in that order.
