System update
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.
Summary
The Nintendo DSi Menu updates are done as separate titles rather than different versions of the same title like the Wii. Each DSi Menu begins with the System ID "00030017" followed by the hexadecimal representation of its TitleID.
