So basically, when you play a DS game (say with a Supercard DSTWO) you have to go back to the Nintendo DS Profile's setting to run the exploit again?
I'm a bit concerned cuz I am gonna buy a 3DS XL soon enough then I'm thinking of shelling 70$ on a Gateway3DS and don't want that to interfere with my warranty.
So, what basically happens is this. You run the Gateway installer on the 3DS, using a DS Flashcart. Then, you're going to switch to 3DS mode using the nintendo profiling part as described in the review. If you want to stop playing, save, press the home button, press x, wait till it goes to menu, then power off. When you reboot, you will need to "reboot" the exploit with the DS Profile. However, if you powered off, then decided to play with the DS Mode with a DS Flashcart, to return to 3DS mode you will need to use the Gateway installer again. As far as I know, there isn't any trackable aspects. Then again, I've never had to send my consoles in.
