Home Menu
The Home Menu is the heart of the Nintendo 3DS. From there one can start games, applications, and access various processes including the friends list. It is launched by NS, and is always running in the background in 3DS-mode except when using certain applications, such as System Settings. The system will normally re-launch Home Menu when the Home Menu process crashes/terminates. When this re-launch occurs while Home Menu is active, Home Menu displays an error message which says to manually reboot the system.

Auto-Boot Kiosk Function
The system checks the game's banner to determine whether the gamecard can be auto-booted. When the Home Menu is initially loaded by NS, it checks Slot-1 for a Kiosk Demo cartridge. If one is found, it will load the application on the cartridge and the home menu will not remain running in the background, or at least not in an operational state. Kiosk demos up to (but not including) New Super Mario Bros 2, utilised a combination, of blocking the functionality of the 'Home' button and kiosk auto-boot to enforce a "kiosk environment". Pressing the power button in this environment caused a shutdown, and the home menu is inaccessible. However if the home menu is fully initialised and then one of these kiosk demos is launched, the environment is the same as if it was auto-booted, except, pressing the power button brings the user to the 'Grey sleep page' instead of shutting down.
From the New Super Mario Bros 2 demo and onwards, a new kiosk environment was introduced. The 3DS will auto-boot the card like before. However, both 'Home', and 'Power' buttons will cause a shutdown when pressed, and the kiosk demo will automatically quit after a set period of time of inactivity causing a shutdown. If the home menu is fully initialised and then the kiosk demo is loaded, the 'Home' and 'Power' act as they would with a normal retail game (the home menu is accessible). But the game will still quit after a set period of time of inactivity, but will instead quit to the home menu.
Attempting to launch kiosk demos on a 3DS which doesn't have the same region encoding, will result in the 3DS will printing "An Error has Occurred" when attempting to auto-boot a such kiosk demo. And not showing the application on the home menu (the latter also happens with regular retail games).
Auto-boot cartridges, can bypass some of the functions of the Home Menu. Auto Booted software:
- Does show usage history in the activity log
- Bypasses Parental controls
- Bypasses Forced Game Card Updates
- Bypasses Initial 3DS Setup
- The console does not have a friends list presence.
Region Lockout
One of the Home Menu's functions, is to regulate region lockout. The region lockout data for any given title is held in the ICN data. There are 6 regions of which have their own region lockout, Japan, USA, Europe(including Nintendo Australia), China, Taiwan and Korea. There is also a value which makes a title exempt from region lockout, and consequently accessible from any region of 3DS.
Effects of Region Lockout
Every 3DS title regardless of location (NAND/SD Card/Game Card) is subject to region lockout scrutiny by the Home Menu. And the home menu treats 'out-of-region' titles by simply refusing to show them on the home menu. No messages are shown on the home menu to notify the user, the title is simply ignored. However out-of-region SD Card titles, will appear and quickly disappear, while all the SD Titles are being processed. In cases where access to the home menu GUI is not needed to launch the title (like in the case of kiosk demos), the home menu states an error has occurred, and launching of the title is stopped.
