Hello, I've just been considering getting a DS TWO+ (Flashcard), mainly for mounting my NDS and GBA roms onto. I also heard that your 3DS can get bricked from these cards but I'm curious of the conditions that this has to happen as I believe that when you're online on your 3DS, it sends information back and forth to Nintendo if there's something dodgy going on. What about when it's offline, not connected to a WiFi? Or does it store the information till when you turn it on or is Nintendo just psychic... So what does it take to notify Nintendo that you're using custom hardware? Thanks, Vouch.
