System update

The System Menu is software shipped pre-installed into every DSi which allows the launching of games from an officially Nintendo certified game card, launching of Nintendo Certified "channels" and DSiWare titles. It run a similar GUI like the Wii.

The DSi runs in certain permission modes similar to the Wii where running backwards compatibility games turns off the extra hardware and clocks down the CPU.

Using the power button you can soft reset to return to the menu while in game (or in a DSi application). Game cards can also hotswapped 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.
