Is there any way to get the seed out of a nand backup file without the original 3DS?
I have an unbanned, but dead Majora's Mask N3DS here, but I do have a nand backup I took before it died.
It would be awesome if I could unban my other N3DS with that seed. Sadly I can't boot it to get to godmode9 or anything
You'll need fuse-3ds , boot9.bin (?), and opt.bin for NAND mounting.
(Start) + (Select) + (X) to dump the *.bin files at startup, and these are found in boot9strap folder. The boot9.bin is the same for every system, but not sure if the same holds true for opt.bin.
