So I have RX Tools EmuNAND 9.2 in my 3ds, but it is linked to my Sys NAND. I was wondering, why should I unlink them, does it damage the SysNAND? Can I update the EmuNAND? Also, I know it is unlinked by formatting my SysNAND, but I have Legit CIAs installed with some progress I don't wanna lose. So is there a way of formatting and getting my Legit CIAs back with their save files? Please someone help me.
