syscall 0x04 should return you to the ps2 browser, if thats what you want.

void ReturnToBrowser()
{
__asm__ __volatile__("

li $3, 0x04;
syscall;
nop;");
}

should take care of it

correct me if i'm wrong.. someone

note, i just tried it using the same method as the loadelf example in ps2lib. it works perfectly fine. it takes at least ten seconds for it to boot to my browser. but that could be because of the sony hdd, or the ps1 disc in the drive or something.

it takes a while with both methods.

also, make sure your start address isn't the problem.

Loaded, rom0:OSDSYS
start address 0x100008
gp address 00000000

as you can see it loads to (i beleive) the default address for what you compile. if you use 0x200008 (like the loadelf example), it works just fine.

you sure you're waiting long enough? it takes a while for the browser to load.
