The official system software is the engine that runs your DSi and DSi XL consoles. Unlike the original DS and DS Lite, the DSi features a menu system that can be updated wirelessly.

While these will bring you to 1.4.5 (they usually update to 1.4 or 1.4.1), they can unstick a console stuck on very old firmware (1.2 or lower).

When the Nintendo DSi launched in Japan in 2008 (and globally in 2009), it was not merely a hardware revision of the DS Lite. It was a philosophical shift. For the first time, Nintendo introduced a console with internal flash storage, two cameras, an audio player, and—most critically—a connected digital storefront (the DSi Shop).
