the radio chanal, alows you to play the radio on the wiimote!(like i said , this is a sudjestion) or an alarm clock. this might be helpfull if you dont have a alarm clock or a ds, all you have to do is make the settings with the wii, then the wiimote acts like a radio! you can change the chanals on it by pressing the 1 and 2 buttons, what do you think?
ps. and dont say theres a mod chip for this, cuz its breaking the law of gameing for that!!!
