1. Kinda, but that's practically a yes.
2. Uhh... you mean installing into sysnand? Yes.
3. Yes, with the HBL cia.
4. Yes, CTRbootmanager + menuhax, as you can set it to automatically boot into emunand.
Thanks for the reply man.
Already installed FBI and HBL with CIA.
Just need to know how to do the step 4, to boot in emunand with GW.
