It could be that Nintendo's relationship with Nvidia goes beyond simply working together on the Switch; if a report emanating from China is to be believed, Nvidia has been given permission to release some of Nintendo's older games on its Shield hardware.
The report was brought to light by industry analyst Daniel Ahmad:
Before we get too excited, it's worth noting that this deal only applies to China at present. Given how difficult it is to sell consoles in that region, it would appear that Nintendo is using smart devices like the Nvidia Shield to crack the market and sell its games. If this is true, Nvidia would benefit by having a major stream of exclusives for its line of Shield systems, which it is looking to launch globally this year.
As Ahmad himself is keen to stress, much of this is rumour and speculation at present, but the fact remains that New Super Mario Bros. is coming to China - yet we've had no word on a Switch release in that region.
If the Shield connection isn't believable, then how else can Nintendo release the game in China? Share your thoughts with a comment below.
