Standard Code

Following a comment on the contribute talk page there is now a Standard Code page for pieces of code that could be useful to anyone
such as return to launcher, rebooting e.t.c

If you are adding to this page please add your code in a source box then put a description of how it works. Do note that at least some of this code is going to be deprecated once that the normal APIs is done.

Code

Return to Loader

typedef void (*Loader_Entry)(void);
Loader_Entry loader = (Loader_Entry)0x80001800;

Whenever you want to return to loader just call

loader();

Reboot

void shutdown(void) {
    __STM_Init();
    STM_RebootSystem();
    __STM_Close();
}

When you want to reboot just call

shutdown();

You will need to include the following

#include <ogc/ios.h>
#include <ogc/stm.h>
#include <ogc/ipc.h>

More reboot code only requiring ogc/ipc.h

void Reboot
{
	int fd = IOS_Open("/dev/stm/immediate", 0);
	IOS_Ioctl(fd, 0x2001, NULL, 0, NULL, 0);
	IOS_Close(fd);
}
