Regardless of what others say and said, it is, I repeat, generally a bad idea to use flash carts on a 3DS at this time.
Every time I see a response like this, it makes me want to bang my head against a wall. I'm using a DSTwo right now in my 3DS. Hell, I even updated the 3DS with the DSTwo in it, and nothing happened. The same goes for my friend too, who is using an EZVi. There is no magic bricking, as it would be illegal. I thought that Rydian would have gotten this silly notion out of the way by now, as he already explained it's downright and flat out against the law for them to brick a 3DS.
I intend no offense to you, but rather offense to these comments, as they're getting pretty annoying by now. This entire brick rumor was started by an anonymous tip on a crappy blog site. Using my super detective skills, I can be led to believe either:
1.) Nintendo started it as a fear tactic
2.) One of those goofs that hates pirates with a passion started it.
3.) Some random guy did it for the lulz.
QUOTEGiven that it will show up in the activity log as a legitimate game cart, I fail to see how it's dangerous. If it WAS being detected, they'd just block it in the first place.
