On retail units, this title is accessible in scenarios where you have to update via the Internet to use certain 3DS software other than the home menu. i.e. using the eShop, on a system version less than the current one. When one selects "Cancel" from here on retail, the system will shutdown. [[NS]] launches SAFE_MODE_FIRM for running this title, when the [[Configuration_Memory|UPDATEFLAG]] is set during system boot.
