    I thought I could just restore my SD Files. How would I fix this? An older backup works, but when booting DSI titles, I get an error, same with Gameboy, but NES games work, and I got my saves back via old backup. These are all ambassador games by the way.

    Why can't you restore it? What is the error?

    My emunand doesn't boot when copying my "Nintendo 3DS" folder. I also have double the stock apps, which go away after launching Miiverse and exiting, or whatever home menu refreshing action.

    Are the backup files and emunand made at the same time?

    See, I inject my NAND.bin, and get my things back, but then I can't update. Injecting lower emunand firmware, and it doesn't boot. I have to clone my 9.2 sysnand, so my emunand is 9.2, then inject my NAND.bin, or Emunand.bin.

    No. I am using a backup I made before even creating Emunand. My saves and stuff work if my emunand is on 9.2, I just can't update. I get a black screen on "Creating Home Menu" or something of that variant.

    So basically, I went from being an upcoming web developer, being pretty good with tech and knowing a bit of code here and there, to being an absolute idiot? Lol, nice.

    First pretend you never made emunand before, sysnand keys will be 1,emunand will be 2,when you made your backup,all games were linked to 1,and when you create emunand,it makes a copy from sysnand meaning emunand keys will be 1 too so when unlinking by formating sysnand,it's keys switch to like ugh...3...so the saves and games in your sd card are still linked with 1 and won't work with 3,3=/=1,but it still works with emunand since both of the keys are 1 and sysnand is 3 meaning that's now unlinked nand, problem if you create a new emunand, it will have the key 3 since it copy's sysnand, and your sd backup files is linked to key 1 since it was made before emunand and you formatted after...get what im trying to say, the sd files don't match with current emunand keys

    To backup your emunand system, backup emunand with a tool and copy the sd files linked with it
