Well that's the question. If they can distinguish between compromised consoles and people who got the game early by mistake then its probably perm. if they can't then there's a chance its temporary.
As far as I know actual cartridges use headers, and game installs (CIAs) do not.
Well they sure are playing with a hacked console too. They did dump the games u know.
Who are they? If I got my hands on a original Sun card because my dad works at Nintendo, why would I need to dump it to play?
