So I'm in a bit of a minor predicament. I've not really been in the scene much lately (the last time I was around, A9LH/menuhax didn't exist!) and now I'm catching back up on stuff. Last night I got A9LH and Luma installed on one of my 3DSXL and it's been working great so far. I'd like to do it on the rest of my units, but I want to make sure all precautions are in order first. So, I decided it'd be prudent to make sure I had current and factory NAND backups for all five of my units (OG, 3x O3DSXL, NDSXL). Problem is, a number of my backups were from back when I only had a single O3DS and one XL, so they're just named stuff like "NAND" and "NAND XL". I don't really remember which XL I had first, and given that I had traded my OG 3DS for a friend's at some point, I'm not 100% certain which units these backups are actually for. Derp! Is there a way to open a NAND backup in a hex editor or some such and find a value I can use to uniquely identify the hardware it came from? So that, for example, I can back up my current NAND and compare them to make sure they match. I don't want to accidentally restore a different unit's backup should I have to use any of them.
