I updated to Luma3DS but I haven't yet found a guide for how to point Luma3DS to an existing EmuNAND. I'm sure there must be a way to do this that doesn't use Gateway. I currently have a rudimentary understanding of the chain-loading process from Luma3DS, and I found a relevant tool called EmuNAND9, but no instructions on how to point EmuNAND9 to an existing EmuNAND folder on the SD card.
