I intentionally keep my systems on the oldest firmware as possible. My 3dsXL is currently still on 7.2.0-14U, which I think A link between worlds forced me into. I got Pokemon Moon for xmas and it wants to update to 11.0.0-14U. I'm not currently using any CFW or flashcards (frankly the 3ds stuff is very complicated compared to my previous experience) but I'd hate to be locked out from being able to mess with it in the future. It seems that right now 11.x is unbreakable, but is it likely that that's just a matter of time? Or are there other options that I just don't understand?
