Homebrew Can move my old ID's New Leaf save file to my new ID's n3DS?

[Thomas Campbell]

I have a backup of my SD card from March 2015. On that SD card I had data for my Animal Crossing New Leaf game. I've also found the specific folder inside "00040000" where the data is located. My only way of accessing these folders is with my PC as the ID of the folder is no longer linked to a 3DS because I formatted it after the backup.

I formatted my 3DS yesterday because I was setting up CFW which I now have. Meaning the backup I took in March has totally different IDs than what I have now.

Is there any way to get back my old save?

Unless you dumped the save with a save manager, it's gone. Sorry.

I didn't :c Are you 100% sure?

If you have a nand backup with the old ID, you can restore it and use JKSM or SVDT. (just be sure to backup your current one first and restore it after!)

I am. Saves and other data stored on the SD card by the system are encrypted with the NAND's ID that is using it. When you format, your NAND gets a new ID.

Specifically, it's the movable.sed file on NAND that determines both the ID and encryption. If you still have this file somewhere (like a pre-format NAND backup) you can still recover saves made using it.

AAAH! I do have a NAND from before I formatted it! So if I restore that, and combine it with the SD card backup it will work??

If I restore the NAND backup to my Sysnand, will that affect my emunand? (My Sysnand and Emunand have different IDs. I don't care about the content on my Sysnand

Your sysnand and emunand have different IDs so they can't mess with each other.

Your SD backup from March 2015 is from your sysNAND, before you had CFW set up, correct? That means, regardless of a format, the ID will still be accessible to your sysNAND (not emuNAND.) From there, you can fiddle around to extract your save with SVDT/Save Manager in homebrew, then re-inject it into your emuNAND.

Unless, of course, this ID folder was from an o3DS, then you need to do what I mentioned on that system to extract the saves.
