The Nintendo DSi system software is a discontinued set of updatable firmware versions and operating system for the Nintendo DSi handheld video game console and its XL variant. Released alongside the console in Japan on November 1, 2008, and later worldwide in April 2009, the system software represented Nintendo's first implementation of downloadable content and comprehensive online services on a handheld platform. Updates were downloaded via the system's internet connection, allowing Nintendo to add features, patch security vulnerabilities, and block unauthorized software. The software introduced a redesigned touchscreen-based interface, built-in multimedia applications including dual cameras and audio recording, and the Nintendo DSi Shop for purchasing downloadable games and applications. Support for the system software concluded with version 1.4.5, released on December 11, 2012, and the DSi Shop was discontinued on March 31, 2017.
