You can't change the delay without changing the code and recompiling it, unfortunately.Yes. I think the button's in the top, right corner.
No. ... but if you don't have SOME USD drive connected (you can play games off of FAT32 or NTFS, too) you'll have to wait while it's looking for the Hard Drive. I think there's a button you can push to make it skip that, though, just that I don't remember what it is.
You could always use something like gecko OS for times when you're JUST gonna be playing from a retail disk (which is all it's made to do)
Well 2.6 has the ping revision that makes it 25 seconds but 2.6 locks up on every game a try when I do certain things. In windwaker, whenever I'm about to do sword training, and in paper mario thousand year door when I open the game menu. Just for example. But on 2.5 I don't have freeze issues.
So would it be possible if someone could make a revised 2.5 that has the 25 second ping delay? I would be so grateful.
