Dumping and Injecting Saves into sysNAND without launching HOS?

[OldGnashburg]

Hi, I want to swap some saves between sysNAND and EmuNAND and vice versa, I've done it before launching clean Atmosphere and no patches or anything and offline. I've done it several times over the years. No ban. But I usually use a fresh SD, vanilla atmosphere and copy my Nintendo folder EVERY time. I've seen that there is TegraScript's that let you dump saves but I don't know anything about it, is that the solution or is there a better way to dump/inject saves without booting Atmosphere?

I recall seeing an article about mounting your NAND on a PC directly and just copying the files over.
Maybe that is the Tegra script thing you are talking about.
Usually people want to get their old saves from the OFW to play on their emummc but you can probably also write stuff back onto the OFW NAND
