System update
The System Menu is software shipped pre-installed on every DSi which allows the launching of games from an official Nintendo certified game carts, "channels" and DSiWare titles. It runs a GUI similar to the Wii's "Wii Menu". The DSi runs in certain permission modes similar to the Wii, where by 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 hot-swapped while in the menu.
Versions
To check which version of the DSi firmware you currently have, open the System Settings and check the lower right hand area of the top screen.
