I've tried to do a system update on my n3ds and i was given and error. When i rebooted and went back into emunand the EMU was gone i went back to plailect's guide and restarted on step 18 ( didnt go back further out of fear of losing my original 3ds data) even after using tiny format it still wont go back to 9.2 emu. What can i do to get it back to emu while keeping all my original 3ds data?
