I'm about to acquire a 9.0 N3DS XL. Since the blue Gateway card isn't required (I have CN), do I need it? I have no plans to downgrade to 4.5, and no desire to play any DS games (to my understanding, the blue card only works on 4.5 and below?). Can I give it to a friend to use as a regular DS flashcard or is there more to using the blue card by itself? Edit: I may have answered my own question... I wanted to give the blue card to a friend who's 3DS is above 4.5, but they can't use it, correct? Or can they..?
