Sorry for asking this but the threads and 3DS info is so old not sure what has changed. From what I have read the Gateway is the best 3DS flash cart? And you need FW 4.1-4.5? I am thinking of buyng a 3DS XL w/ 4.5 (there are tons of ebay) and getting a Gateway cart. I just want to make sure that's still the way to go? Thanks.
