I was wondering if when editing a save for Sword and Shield do you just need to edit the "main" file, or do you need to do the same for the "backup" file as well? Because I noticed both of these files register as saves when used in PKHeX and am not sure if it's okay to just change one file without changing the other.
Not sure if this has been reported already, but the RotomDex continues to refer to you by your original Trainer name rather than the new one after changing it. For every other case, the dialogue and signs reference the new one.
