I managed to get myself a New 3DS recently and have been stuck trying to decide what to do. It's been newly set up without an NNID and otherwise untouched. I have an old 3DS on 9.2.0-20U with a compatible SuperCard DSTWO. Please keep in mind that while I'm familiar with DS flashcarts, I'm quite unfamiliar with and overwhelmed by the recent developments on 3DS hacking despite looking through the forums as best I can. My intent was to get into the 3DS flashcard scene with a Gateway on my old 3DS and keep the New3DS unhacked and updated so I can get all the newest eShop games. I also wanted to transfer my NNID and associated data from the old 3DS to the New3DS, but it seems like both systems either need to be updated to the same firmware or hacked to do a system transfer. Before I decide on anything, I had a few questions I'm hoping to get answers to... 1) I believe updating my old 3DS from 9.2.0-20U to whatever is the newest firmware would make it incompatible with a Gateway card. Is this true? If I get a Gateway card without updating, is it going to be ready to load 3DS ROMs out of the box? 2) Would doing a system transfer wipe the pre-installed games (i.e. pkmn red and blue) on the New3DS or would it simply merge the transferred data with the pre-existing data? 3) Would I be able to somehow spoof 10.2.0-27U on my old 3DS to get my NNID on the untouched New3DS via system transfer? I'd still want my old 3DS to be compatible with a Gateway card. 4) What would it take for my New3DS to be compatible with a Gateway card? If this necessitates the New3DS getting hacked and prevented from updating, are there any downsides (i.e. no access to eshop)? Any help is much appreciated. Much thanks in advance.
