I have a 3DZ Rom of my Retail ACNL Cartridge (using the same Unique IDs) that I'd like to restore WHOLE the save from to my retail cartridge. Since I'm using the whole save there is no worries about Secure NAND Values, and differences in unique encryption keys isn't an issue because I always ran it as a 3DZ with same Unique IDs thanks to being a direct rip of my retail cartridge. I've already copied/ripped the save data from the 3DZ to a .SAV with @ETNWIND 's "Card2/Nand Save Backup & Restore Tool" (220.127.116.11?) Problem now is, how does one actually WRITE the save back to the retail cartridge from the matching 3DZ? or perhaps a way to decrypt and extract the save and push it to the cartridge using one of the various *Hax capable save managers? or is there no way outside purchasing a save dongle?
