The Nintendo 3DS is a gaming handheld by Nintendo, which can produce "3D effects without the need for any special glasses." It was released in March 2011, the portable succeeded the Nintendo DS series of handhelds, which primarily shares the handheld console market with Sony's PSP (PlayStation Portable). The Nintendo 3DS features backward compatibility with Nintendo DS series software, including DSiWare programmed for the Nintendo DSi.
The Nintendo 3DS has two screens; the top screen is a 3.53-inch 3D screen with a resolution of 800x240 pixels (400x240 pixels per eye, WQVGA) that is able to produce a stereoscopic three-dimensional effect without 3D glasses, while the bottom screen is a 3.02-inch non-3D touch panel with a resolution of 320x240 pixels (QVGA). The 3DS weighs approximately 8 oz. and, when closed, is 5.3 inches wide, 2.9 inches long, and 0.8 inches tall.
Like the Nintendo DS, it features the usual A, B, X, Y, Start, Select, and Power Buttons with the D-Pad.
The system features several additions to the design of the original Nintendo DS, including a slider on the side of the device that adjusts the intensity of the 3D effect, a round nub analog input called the "Slide Pad", an accelerometer, and a gyroscope. In addition, there is an infra-red communicator port situated on the top of the unit.
The 3DS has two cameras on the outside of the device, capable of taking 3D photos, as well as a camera positioned above the top screen that faces the player; both cameras have a resolution of 640x480 pixels (0.3 Megapixel). The system also has 3D movie playback capability, and was shown able to record 3D video content.
Nintendo has made deals with Warner Bros, Disney, and DreamWorks to deliver 3D movies including Warner Bros' Legend of the Guardians: The Owls of Ga'Hoole, Disney's Tangled, and DreamWorks' How to Train You Dragon.
It is compatible with both Nintendo DS and DSi games, and a new generation of 3DS games. More than twenty companies have signed on to develop for the 3DS, currently supporting a list of over 70 titles.
The Nintendo 3DS cartridges will hold 2GB of game data and look almost exactly the same as those of the current DS. However, there is a small tab jutting out on the one side, most likely to prevent 3DS cards from being inserted in the 1st generation DS. It has also been hinted that the 3DS would sport an e-reader app as well.
The 3DS possesses Wi-Fi capabilities and periodically searches for Wi-Fi hotspots and other 3DSs without user input, and will be able to receive data from the Internet or other 3DSs while in sleep mode. The system supports multiplayer gameplay via a local wireless connection or over the Internet.
The system has been shown in five color schemes: black & blue, black & red, black & grey, black & gold, and black & purple.
The latest system update opens a theme shop, allowing you to give your Home Menu a new look.
