Hi, I have a 128gb SD card full of NSP installed games. Recently, I've discovered that I have to do a firmware update in my switch, and I already have the lastest beta release of SX OS and the firmware to download with choidujournx, like I always do.
What I do not have is the minimum 30gb space in my SD card for the NAND backup that I will do before the firmware update. I was wondering - instead of deleting some of my games and redownloading them all again (game + updates + DLC), can I backup some folders from the Nintendo/registered folder of my SD card (A.K.A where the NSPs are installed) to my computer, do the NAND backup and then reinsert the folders right back to my microSD? Does this work without game corruption?
thanks for the help!^^
