Use SX OS Switch, have 10.2. Updated (xbns) with 10.2, latest shown. Now when starting Super Smash Bro Ultimate get a message that system needs to be updated. argh..... Wanted "Steve" character added. Can I "downgrade" the game by installing an older update version, or will it stay at unplayable newer version? Or, could I uninstall SSBU and then reinstall but with an older update? Does anyoneone know how you get the "Steve" character? This Switch never goes online.
