So I know the last digit means what browser it has. People have said it needs to be at least a '7' for rxTools to work. Is there the same limitation for Gateway? I just got a new old 3DS that I want to set up and post to my sister so we can play Triforce Heroes together. It has firmware 2.1.0-4E. The only cartridge I own is Majora's Mask which I think updates to like 8.1 or thereabouts. If I update it with Majora's Mask will I be able to use the Gateway on it and then be able to install 9.0-9.2 and eventually set it up with auto-booting rxTools? I also remember people saying you can't use sysupdater with Gateway mode. I also have a copy of Cubic Ninja if that helps. A bullet point list saying what restrictions there are on every browser version would be great (unless everything needs '7' or higher).
