I recall reading somewhere that your emunand was possibly tied to your hardware, but here's my thought process: So I had an OG 3DS that had my profile tied to my nintendo network ID. I'm all digital with my games, and so when I set up Gateway on my 3DS XL, I wanted the sysnand profile that had all of my digital purchases to go there. My gateway is for fan translations and testing out games before I pick them up. Anywho, I updated my emunand to the latest firmware, and then did a system transfer so that my sysnand from my old 3ds was on my 3DS XL. Well, I recently repaired an old 4.x firmware midnight purple 3DS that I'd like to use, and I began mapping out in my head how I would go about transferring emunand to emunand to use the midnight purple one for a while. Well, I got to thinking, since my Emunand is separate from my sysnand (if I understand correctly), can I just take that memory card and boot gateway on the other 3DS? If I understand correctly, my emunand is basically a separate virtual system right? I know I'm not using the proper terms, but you get the general idea of what I'm trying to say, I'm sure.
