Long story short I've got a little girl with a 2DS OOT and Power Saves, I can get access to the homebrew channel now is there anyway to install FBI? As far as I'm aware there is not but thought I would check first.
no, you will either need a HW mod, Transfer from another 3DS, or a NTRboot compatible flashcardSo I can get FBI installed on 11.6 using just the OOTHAX?
You'll want to do the ntrboot method (will require a compatible DS flashcart). https://3ds.guide/ntrbootSo I can get FBI installed on 11.6 using just the OOTHAX?
