The system's iconic feature for which it is named is its autostereoscopic top screen, which projects an illusion of 3D depth to the screen's contents internally through use of a parallax barrier; or, as the console's marketing puts it, provides "3D graphics without needing special glasses". In addition to its own library of games, the system is backwards compatible with almost all Nintendo DS games and with the enhancements previously unique to the Nintendo DSi. Like the Nintendo DSi and unlike all portable Nintendo consoles preceding the DSi, the 3DS is subject to a region lock divided into four regions: Japan, the United States and Canada, Europe and Australia, and South Korea. A variant on the console, the Nintendo 3DS XL (ニンテンドー３ＤＳ ＬＬ Nintendo 3DS LL), was released in mid-2012; this variation is larger than the standard model and features larger screens, and is intended as a complement to the basic model rather than a successor.
A special edition model of the Nintendo 3DS was produced and sold for Fire Emblem: Awakening in the United States and Japan. This model, a "Cobalt Blue" console with Awakening themed decal printing on its lid, was packaged in bundles with copies of the game (a physical copy in Japan and a pre-installed digital copy in the US). The European release instead featured a Nintendo 3DS XL with Awakening decals.
