Nintendo DSi

The Nintendo DSi is the third model of the Nintendo DS family, following after the Nintendo DS Lite. It was originally released in Japan in late 2008, followed by most other regions in 2009, and in South Korea in 2010.

Aside from being a remodel, the Nintendo DSi serves as a partial successor to the Nintendo DS due to several of its newly-introduced features, most notably its unique software and games. Some of the Nintendo DSi's other features include two cameras, music playback functions, a built-in internet browser, slightly larger screens, and a Wii-inspired home menu. The Nintendo DSi has some built-in software, although a majority of its software was downloadable from the Nintendo DSi Shop, prior to its discontinuation in 2019. Nintendo DSi software could be stored on either SD Card or the system's internal memory, although some of the essential built-in applications, such as the System Settings, can neither be moved nor stored on an SD Card.

In China, they were released under the iQue brand, earning it the title iQue DSi. Every iQue DSi came bundled with a digital copy of Nintendogs. The two candidates to be bundled digitally with the iQue DSi were Nintendogs and New Super Mario Bros., and iQue picked the former because Nintendo least wanted to see it pirated and sought to attract a casual demographic. In China, New Super Mario Bros. was physically released as an iQue DS title in July 2009, 5 months before the iQue DSi was released.

In 2009, a remodel of the Nintendo DSi was released, the Nintendo DSi XL. Eventually, in early 2011, the entire Nintendo DS family, including the Nintendo DSi, was properly succeeded by the Nintendo 3DS.

Nintendo DSi-enhanced games
Some Nintendo DS games have enhanced features only accessible if played from a Nintendo DSi. One example is that games that were compatible with Nintendo Wi-Fi Connection (prior to its discontinuation on May 20, 2014) could also utilize the and  wireless standards as well as the  standard, the only wireless standard that was supported by original Nintendo DS units.

Nintendo DSi-enhanced games have a few distinctions, including a 10-character game ID divided by two dashes on the cartridges, located on the bottom-right of each label, and the prefix  (codename Twilight for DSi) instead of   (codename Nitro for DS). Like the iQue DS cartridges, Nintendo DSi-enhanced games are also region-locked.

Limited editions
A special limited edition Nintendo DSi was sold on Friday, November 27, 2009 ("Black Friday") in the United States only. It was available in Metallic Blue and came preinstalled with five Mario DSi games/apps, namely Mario vs. Donkey Kong: Minis March Again!, WarioWare: Snapped!, Dr. Mario Express, Mario Calculator, and Mario Clock. A red DSi XL also came in a special Super Mario Bros. 25th Anniversary Edition DSi package.

Sales
As of September 2014, the Nintendo DSi has sold 28.44 million units, more than half of the 12.93 million Nintendo DSi XL units sold at the time. The DSi's front has a camera lens, and another, smaller lens is located where the mic was positioned on the Lite, allowing for photos to be taken with the DSi open.

Trivia

 * Budgy, a parakeet character from the Nintendo DSi, has a phrase about Princess Peach infiltrating a castle in the Nintendo DSi Sound application.
 * If the player records a sound and waits, the Super Mario Bros. theme starts playing using the recorded sound as instrument.
