I do go online. I have one of the new better battery model switch that cant be modded which is the main console that I use daily, then I have one that is running SXOS. I use the one that can be modded with stock firmware most of the time. All of the games that are on both systems are games that I have purchased from the Nintendo store. When I want to use a cheat I will put the exploitable switch in airplane mode and then reboot into SXOS then run whatever cheats I want to max out a character in a game the save the game. Then reboot into stock firmware and let the Nintendo cloud save make a backup for me. The boot into my none exploitable switch to download the modded save and use it.
I know it is cumbersome and mostly a waste of time but it works and has been working for some time and as of yet haven't got a ban on it "though I am under no illusion that a ban is likely at some point".
Doing this requires both consoles to be on the latest firmware for connection to Nintendo servers.
Sorry buddy, I meant to send my message to the OP. Been a crazy day lol
Nice. Good little method you have there.
