Gamecube Hardware
Alternate starting sounds: Hold Z while the Gamecube logo appears to hear new sounds. Hold Z then about one second later hold A to hear another sound. Insert four controllers then hold Z on each of them while the Gamecube logo appears to hear different sounds. Control starting logo: Hold A while the cube bounces down to form the \"G\" logo to spin it. Set system time and options: Hold A while powering on the system. Alternately, hold A while the cube rolls around the screen. Alternately, turn on the Gamecube without a disc. Wait until the opening sequence is over and you will be able to set the time and date on the system, delete memory files (if there is a memory card inserted), and set the sound and screen position.
