That way, everything that's currently on your sysNAND is transferred to your emuNAND, since the emuNAND is meant to be dirty anyway.why should I make my emunand before restoring my sysnand?
Nothing you did in Hekate when you first hacked your Switch affected your NAND, so your sysNAND wasn't immediately made dirty. If you did homebrew, NSP-installation, etc. before making a NAND backup, then the NAND backup is dirty.also wouldn't the method I used to initially hack my switch in turn dirty my sysnand? I mean I had to hack my switch to setup a nand backup in the first place?
