So I've got A9LH installed and I created a 9.2 emuNAND. I've got all the files on my SD card. I was told I would have to hold R to boot into the emuNAND, then load Homebrew Launcher, then Gateway, and select System Mode so it'll boot into sysNAND with the Gateway launcher. I tried that, and get a black screen when I try to load Gateway launcher. What did I do wrong? Also, should I install MenuHax on the emuNAND?
