Why is http://gbatemp.net/threads/region-free-cart-loading-with-emunand-no-flashcards.360261/ no longer a recommended method? Does it not work anymore? The reason why I ask is because I was thinking about selling/trading my 3DS XL Golden Zelda edition for a 4.x model so I can import 2 games / get them from conventions I frequent. I read somewhere that once this patch is applied that you can update past 4.x to current 7.x firmware and the patch would still be intact. Is this true? If that method up above is not to be used, is there another one that works on FW 4.1-4.5? Thanks.
