On a 100% clean Sysnand there is zero risk. You can update FW, upgrade your GC, buy games, update games and play Online as long as you don’t put anything dirty on it.What do you think my ban risk will be if I connect online to update System FW? IS it safe to update games also?
Once you hack your switch you should create an emunand. Emunand is an exact but independent copy of Sysnand that should be kept offline using exosphere and dns:mitm. If you happen to put nsp, xci, cheats, etc on this version it will not get a ban because Emunand is kept offline.
This is the ideal state. It’s when people deviate from the ideal state that things can get tricky.
Atmosphere by itself will not get you banned according to SciresM himself. He and many of the Devs go online with their clean CFWs without issues. Folks that don’t run as clean as their team get in trouble when they do things on emunand under CFW and then do something silly like run that same CFW on their Sysnand and forget they had cheats or other bannable software running from their SDCard that is now connected to Jinty. The best way is to keep everything separated and you’ll have nothing to worry about.
E: once your Switch is hacked, there’s no reason to run a GC anymore unless you happen tomhave a GC than needs Online…so really edge case.
