BootMii doesnt support the wii remote. If you don't have a gamecube controller, you will have to use the (physical) POWER and RESET buttons on the wii itself.
@The Real Jdbye, I thought about that and I have blank DVD's and Blurays but honestly after like 90 songs I just listen to it a couple of hundred times toss it out and burn something else or have like 2-3 CD's. Florida here the heat in the car tends to ruin the CD's after like a few months even commercial pressed ones don't last too long.
