I've been doing reading all day trying to figure out exactly what I need to do to use EmuNAND without a Gateway 3DS. I have EmuNAND already set up. I used my Gateway for a long time, but I would rather be able to just use Ninjhax or MSET to boot EmuNAND. I have a New 3DS, 9.0.0-20U. I see that ReiNAND seems to be the only CFW that supports EmuNAND right now, on N3DS. I got that set up and was able to get into EmuNAND, but I don't know how to install CIAs. I tried using FBI to install BigBlueBox in my EmuNAND but I got a signature error because I was using FBI through Ninjhax. I used to just load backups as .3DS through the multirom menu, but I will install them as CIAs when I figure out how to install CIAs. If anyone could provide some direction, I would appreciate it!
