perhaps a stupid question, but aren't you supposed to be using emunand when messing with games? also, what's the point in downgrading odyssey? I also have the digital version, but I'm legit, so there was/is no way to downgrade. my guess is that you wouldn't be banned simply for playing a downgraded game as a cartridge on a system that's not online might be on 1.0. and, the system doesn't automatically update games unless their on the home menu row iirc, so theoretically, an official user could be on 1.0 even today. I don't know about modding a switch though, but I wouldn't do it on sysnand if it were me.
