Hello! I have just bought an O3DS XL from Ebay that has the firmware: ver 4.2.0-9U on it. I am wondering which flashcart would be best to buy, since, I have never bought a flashcart that can play 3DS games on it before. The only flashcarts I've have had is a R4I Gold and a DSTWO. I was thinking about getting a gateway or a DSTWO Plus, but, I don't see much information on the DSTWO Plus yet. What should I do with the 3DS before buying a flashcart, just to be safe and make sure nothing goes wrong? Thanks.
