Build a business case: developing custom apps

What is it?

The Nintendo 3DS is the successor to the Nintendo DS handheld games console and can produce 3D effects without the need for special glasses. Not only can users play games in 3D, but they can also take pictures with its two cameras, as well as network with Wi-Fi. More on that later.

So how exactly does the screen work?

The screen uses an auto-stereoscopic parallax barrier which cleverly sends a different image to each eye, fooling the brain into seeing a 3D output. For the technical lowdown of exactly how this functions, here's an insightful article on auto-stereoscopic technology.

Is it actually unhealthy for my eyes?

While it is recommended to take breaks from viewing any console, Nintendo says the breaks should be more frequent with the 3DS. It has also put out a warning that kids under the age of six shouldn't use the 3D effect at all, as their eyes aren't yet fully formed and it could stunt their optical development. Recently, however, doctors have claimed it could be used to pinpoint early signs of eye disease, but sustained use isn't recommended.

I've heard terrible things about the battery life - is it poor?

Unfortunately, yes. The battery life on the 3DS is pretty shoddy, with an average span of 3-5 hours. When playing 2D DS games, that figure increases to between five and eight hours, but it's still a far cry from the DSi, which had a battery life of up to 14 hours. Still, as time goes on we will almost certainly see a range of battery boost options, such as the Nyko Power Pak+ pictured below.

Nintendo 3DS

Is it backward compatible with older DS games?

It certainly is. All DS games will work on a 3DS, provided they didn't use the Gameboy Advance slot. They can be stretched too to fit the new resolution, should you wish to tamper with the proportions slightly.

Will it make my DS games 3D?

No.

What's this I hear about it being region-locked?

Unfortunately, all 3DS consoles are region-locked for 3DS games. Nintendo really missed a trick here, after all, its a PORTABLE console. DSi enhanced games also remain region-locked, but you'll be pleased to know all Nintendo DS games are still region free and those old Japanese cartridges you own will still run on your shiny new European 3DS.
