Code Snippets
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.
#include <gccore.h>
static GXRModeObj *rmode = NULL;
// ...
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
#include <unistd.h>
// ...
exit(0);How to use the Wiimote
A separate article is available: How to use the Wiimote.
Reboot Wii
Use:
#include <gccore.h>
// ...
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.
