There’s no going back from a genocide run without deleting your save file entirely. It’s like Undertale’s tough love for completionists!
Sorry, buddy—if you completed a genocide run, the game remembers it forever, even after resetting. You'll always carry that baggage with you. No true reset.
To reset Undertale on the Switch after a genocide run, you need to delete the save data for the game from the system settings. Just go to System Settings > Data Management > Delete Save Data and select Undertale. You'll be starting fresh!
