Video Auto-Detect Routine

The libogc included in DevkitPPC r15 does this for you with one function call. Here is the video detect code from the DevKitPro Wii example.

rmode = VIDEO_GetPreferredMode(NULL);
VIDEO_Configure(rmode);

Exit to Loader

It's a good idea to add some way to return to the loader, otherwise you have to reboot you Wii to exit.

// Just call the exit() function to go back to the loader
// Returning from main also works, since that calls exit for you
exit(0);

How to use the Wiimote

A separate article is available: How to use the Wiimote.

Reboot Wii

Use:

SYS_ResetSystem(SYS_RESTART,0,0);

Or use SYS_RETURNTOMENU for a "soft" return to the system menu, SYS_POWEROFF to shut down the wii (automatically to the appropriate Idle or Standby mode, depending on the WC24 setting), or SYS_POWEROFF_STANDBY or _IDLE to specify the mode and override the system setting.

General Programming Tips

• Keep your code commented throughout; it helps others help you.
• Any unused code should be deleted out of the program, unless it is a program for teaching people.
• If someone does the same thing in a more efficient way (i.e. faster and/or in less code), accept it and learn from it.
