System Menu

The System Menu (DSi Menu) is software shipped pre-installed on every DSi which allows the launching of games from official Nintendo certified game carts, "channels", or DSiWare titles. It runs a GUI similar to the Wii's "Wii Menu". The DSi runs in permission modes similar to the Wii, where running in backwards compatibility mode turns off extra hardware and down-clocks the CPU. Using the power button you can soft reset to return to the menu while in game (or in a DSi application), similar to the "Home Menu" on the Wii. Game carts can also be hot-swapped while in the menu.

The Nintendo DSi "System Menu" updates are made up of newer components of one or more system titles, as well as a new version of the Version Data bundle (which contains the user-visible version number).
