Meh, people think one site that a bunch of people used getting taken down means the end of the world.
If there's one thing my sixth grade computer teacher taught me it was that once something is on the internet, it's always on the internet. She used this to be like "BLAH BLAH CYBER BULLYING IS BAD" but really it means once you upload a file, odds are it'll be somewhere else on the internet. Unless the entire internet is brought down there will always be a copy of every DS ROM out there, you just have to look hard enough. Same goes with pretty much any game that has been dumped or almost any uploaded file of worth on the internet.
