Think about it for a while; Why do Nintendo still allow us to install tickets and download pirate games directly from their servers? They surely can stop this with a simple check on the bought games, like they do for legit bought games can't they?
Also, if multiple homebrew can use security flaws to gain control and disable checks, why can't they use security flaws in the homebrews to wreck our hacks? I'm pretty sure there could be many.
Another thing, why don't they issue permanent online bans? I'm not really sure but I think there could be N ways to check if an online user is a legit owner of said game. Hell, even when they DO detect pirate games online (same header roms on flashcarts) they issue simbolic bans of no more than a few weeks.
I don't understand why they sometimes try so hard to fix things that are not so harmful (userland homebrew) while allowing such incredible exploits for pirating.
I don't understand, really. How long will we be allowed to keep those methods?
