Ganz blöde Idee. Wenn du mit dem editierten Savegame online gehst, kannst du auf deinen Bann schon mal warten.

Not true. I've been going online with hacked savedata in Pokemon and New Horizons since both came out and I'm fine.

I've been going online with Atmosphere since about November 2019 very regularly, and I'm fine. From what I've gathered from a lot of people in the scene, the main causes of bans are:

1. Installing anything to the Home Menu (whether homebrew software or piracy)
   
2. Piracy through other methods
   
3. Custom profile icons
   
4. Cheating in games (not stuff like save editing, like item cheats and such)
   

I use LayeredFS to load mods in Smash and MK8D, and I've done save editing like I said and I've been fine.

I used to use Checkpoint but now yes, I primarily use JKSV.
