GameCube System Cheats (GameCube)

While powering on the system, hold B until the message "Would you like to switch to 50hz
mode?" appears. This allows you to switch the screen refresh to match that of PAL games.
If playing on a PAL system, the message will be "Would you like to switch to 60hz mode?",
allowing the screen refresh to match that of NTSC games.

While powering on the system, hold A or 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.

While the cube bounces down, hold A to form the "G" logo to spin it.

While the Gamecube logo appears, hold Z to hear new sounds. Hold Z then about one second
later hold A to hear another sound.
