Well I'm not sure if this's true; if true it's a quite clever thing ..... and mean.

Here's an interesting bunch of rumors for you guys. While we already know that various flash carts work on the 3DS when playing DS games, it seems like that might have been planned from the beginning. Rumor has it that the 3DS can actually keep a log of activity that will make note of whether a flash cart was used or not. Furthermore, retailers will be able to check this log, and if they see pirate activity they will not be able to do a trade-in.

That's not even the worst part. We're also hearing that the 3DS will see an update that will block the system from booting up if you've used a flash cart. In other words, if you're playing a pirated game, Nintendo could send out an update that kills your system! Finding a workaround for that might be a bit tough, and quite bothersome as well.

So I can have my 3DS bricked for playing back-ups of games own? Not cool, Nintendo :( 

If this is true, then great; Nintendo can take down the space pirates once and for all!

Mother Brain and Ridley will not be pleased...

This may show that software sales are more important to Nintendo, as they are potentially losing millions of hardware buyers from this.

Not me, though. I'm a ninja, not a pirate.

Oh no!

 ... i really really hope this is true!! go nintendo go!!!

ITS ME :D

what? they can damage my hardare? the one i legally bought and can do with wathever i want? how is that possible?

By stealing games, that's how it's possible. They can legally damage your system for playing software that you ILLEGALLY obtained. Deal.
