Unlike Microsoft and Sony, Nintendo had restricted what it let video-makers share online and took a slice of advertising revenue from YouTubers.

Its new guidelines lift most of the restrictions and no longer ask gaming vloggers to register for Nintendo's revenue-sharing scheme.

Nintendo said it was "humbled" by its fans' loyalty.

Many video-makers had complained about Nintendo's policy and avoided sharing gameplay videos online, because the company often filed copyright claims on the content.

Previously code-named NX, now named the Nintendo Switch, the device looks like a tablet computer with controllers that attach to its sides.

The device was revealed in a short "teaser" video posted on YouTube.

One analyst said the device could be Nintendo's "last shot" at selling a home console.

Super Mario Run will be released in Apple's App Store in December in more than 100 countries.

Nintendo, which announced the tie-up at Apple's launch event for the iPhone 7, saw its shares jump 18% before falling back to around a 13% rise.

Nintendo shares dropped by 17.7% after they more than doubled in value since the game's launch on 6 July.

Pokemon Go was developed by US firm Niantic and Nintendo said profits from licensing and fees would be limited.

However, even with the decline, Nintendo shares are still up 60% since the release of Pokemon Go on 6 July.
