I have a v1 Switch which I am using Atmosphere with. I play my retail games on physical, and everything else, well, on emunand. I always paid attention to only run CFW on the Emunand, so that Nintendo doesn't bust me. Now I have the problem that I need to move a save game of mine to an Emunand on another switch. I know that JKSV is the right choice to do this, but I am bloody afraid to enter CFW on Sysnand.
So can someone tell me, how safe is it to use Atmosphere on sysnand, with the sole purpose of entering the HBB and using JKSV for exporting a save?
