I've been working on extracting a localfriendcodesseed_B from a NAND backup without the original hardware, I've made a lot of progress so far but I need to know how to do something...
Is it possible to format an emunand on an SD card that is O3DS-sized, but doing it on a N3DS? I only have a N3DS right now but my backup is O3DS, and Emunand9 only seems to format it N3DS-sized, so I can't do anything with the backup.
I'd like to format the SD card into a O3DS-sized emunand, without an actual O3DS on hand... if this isn't possible then I'm stuck, but basically:
1. Format an SD card to emunand
2. Import your NAND backup from a different and unbanned system into it
3. This will brick your emunand, but
4. Load Decrypt9 and extract LocalFriendCodesSeed_B from emunand
It worked for my N3DS backup.
