wow just wow. you can update your emunand to 11.1 without issue. 11.1 breaking menuhax has nothing to do with emunand users. you are updating your emunand NOT the sysnand. the sysnand stays on 9.2 with its menuhax install. you will not need another way to get into emunand as what you're using now will not change.
I've been lied to! Ohwell, it made me transition to a9lh anyway but good to know for my other 3ds. Thanks for the info.
