I just bought the old 3DS XL. Version 10.1.0-27U What flashcard supports this version and can play 3DS games as well as older DS games? Also, what do I need to know. Is automatic updating enabled on the device by default or how do I ensure it will not update? Edit: I would also like to know a website to buy whichever card is recommended. I'd like their official site and the reseller that you have used.
