Good news, I finally installed A9LH !
And you were clearly right when saying it's far better than SysNand + Emunand RxTools x) Stability, Boot speed ! Wow ! Thank you all, dev and guys who told me "omg do it it's better omg rxtools is outdated omg" x)
I just have a question, because i'm curious.
When you install an Emunand, the internal memory became divided, and there is an hidenn part into the SD for the Emunand, because there is both SysNand and Emunand, like 2 OS.
A9LH (plailect guide, with Luma), when I boot I can see on my System Settings i'm on "Sys 11.0", so i'm not in an official SysNand (Or it'll be "Ver. 11.0"). My question is: In my 3DS, is there still 2 OS with a hidden SysNand "official" in 9.2 like with RxTools Emunand+Menuhaxx ? Or it's completely overwrited by a modified one, this one, "Sys 11.0" ?
