I'm a little confused about what exactly is safe to edit on my Pokemon Shield save and what isn't safe to edit, with regards to getting a ban, as I'm planning on running CFW on my SysNAND to get the save data, then I'd restore it back. I would take my switch offline while I edit the save. Can I edit my trainer's ID number (at the very start of the game, before I connect to any pokemon home servers)? Can I edit my party pokemon? My box pokemon? Is it all safe assuming I don't do anything silly like illegal moves/pokemon?
I haven't actually done it yet though, but are there any tutorials for extracting my save from the sysnand with cfw, then restoring it and not getting a ban, or is that too risky? are there other ways of getting/restoring a save to edit while still keeping online functionality?
Is it even possible to edit a save and still connect to pokemon home?
