ok I recently got a 3ds xl and was looking at the options for running flashcards. From what I've read I thought the acekard2i works with all 3ds's but on a sale site it lists 3DS 4.3 here http://www.modchipcentral.com/store/Gateway-3DS-USA-CANADA.html. And when reading about the gateway card it says 3ds v 4.5. Which from what I have read is the highest firmware version you can run it on. So you can only run acekard on 4.3 and gateway on 4.5? Is this correct, I am just seeing a lot of conflicting information as I try and search for my answer. Currently my 3ds is running 6.3.0-12u. Is there a way to downgrade it? Although I do plan on purchasing the new Pokemon so that would most likely need the new update? Thanks in advance for your help.
