The Nintendo 3DS is a handheld game console launched in 2011 as a successor to the Nintendo DS. Its main feature was the ability to display stereoscopic 3D effects on the upper screen without the need for special glasses. Nintendo’s previous attempt at a 3D handheld game console (the Nintendo Virtual Boy) was a commercial failure, and required a special headset to view monochrome 3D effects.
The Nintendo 3DS competes with Sony’s PlayStation Vita handheld console.
Several versions of the 3DS have been introduced since its launch, including the 3DS XL with a much larger screen, an entry level 2DS (without the clamshell form factor or 3D facility), and the ‘new’ 3DS and 3DS XL with a faster processor and other upgrades.
It is backward compatible with the Nintendo DS and DSi, and Game Cards for these consoles will fit into the 3DS. Games for the 3DS are prevented from being inserted into the older DS/DSi by a small lug on the card. 3DS Game Cards can hold between 1 and 4 GB of game data (compared to the DS card which held between 8 and 512 MB).
As well as loading games from ROM cards, the 3DS can connect to the Nintendo eShop to download games. Games, audio and picture files can be stored on a Secure Digital or SDHC card (or microSD on the new 3DS/DS XL)
Despite disappointing early sales, the 3DS family become very successful and as of September 2016 had sold over 61 million units.
