So, menuhax + Gateway has worked fine for me. It has served me well so far, but their flashcart was expensive when I got it, and I never really wanted to rely on unknown, shady developers for support. As I understand, there are far better options nowadays, which are free, more versatile, and a lot more future-proof. I have an O3DS XL. I've been using a 9.2 sysNAND (that I only use for GBA games), and a 10.7 Gateway emuNAND that I've had since last year. What I want is to completely stop using Gateway, and finally move on to A9LH + Luma3DS (formerly AuReiNand) with updated sysNAND. I know how to convert my old 3DS/3DZ games to CIA, and how to export my old Gateway saves and import them to the new CIA copies. What I haven't seen is a proper guide on how to transition from my existing Gateway emuNAND to an updated sysNAND using Luma3DS, while keeping my NNID and everything else. I must have missed that transition phase when all those questions were being answered. Is there a way to safely inject my old emuNAND as sysNAND once I set up A9LH and all that? Or will I have to continue using it as emuNAND? Will I have to convert it to RedNAND? I'm quite confused. Thanks for any help guys.
