The Nintendo 3DS is the successor to the Nintendo DS line of handheld gaming systems. The 3DS is capable of producing 3D effects without the aid of special glasses. Nintendo unveiled the 3DS at E3 2010 alongside announcements for several first- and- third-party games. Nintendo 3DS titles are designed specifically for the system, though the 3DS is also backward compatible with games from all iterations of the Nintendo DS, and can also play downloadable DSiWare games programmed for the Nintendo DSi.
Though the Nintendo 3DS’s inner hardware is quite a bit more powerful than the innards of the Nintendo DS family, the outside casing should strike a familiar note. The clamshell design remains from the Nintendo DS, as does the two-screen setup. The top screen of the 3DS displays 3D visuals, whereas the smaller bottom screen retains the DS’s touch-sensitive functionality. There are still some notable aesthetic differences between the Nintendo DS, Nintendo DSi, and Nintendo 3DS: The 3DS is capable of taking 3D pictures, whereas the DSi is not, and the 3DS also has an analog nub situated above its traditional cross-shaped d-pad.
