New Super Mario Bros. Wii Coin World (Japanese: New スーパーマリオブラザーズ Wii コインワールド, Hepburn: Nyū Sūpā Mario Burazāzu U~ī Koin Wārudo).
While the wait continues for back catalogue titles to arrive Nintendo Switch, owners of the Chinese version of Nvidia's Shield have been playing a quartet of Wii games for the last few months. These are entirely official emulated titles co-developed by both Nintendo and Nvidia, and as the same Tegra X1 processor powers Shield and Switch alike, we have to wonder: is this our first look at how games like Super Mario Galaxy may look and play on the hybrid console? 
If so, we're in for a real treat. First of all, it's worth pointing out just how difficult it is to access these games, even if you already own an Nvidia Shield device. Accessing the title requires a Chinese console (the way we did it) or else visiting Nvidia's Github, downloading and compiling the Chinese version of the operating system and then flashing your console.
We attempted the latter but gave up owing to the sheer amount of work required to get the simplest of tasks done. Getting a machine sent across from China actually turned out to be a lot easier and faster. Once you have the hardware situation resolved, the only way to access the software is via a VPN, while actually paying for the games requires using Chinese social media platforms WeChat or Alipay, where a Chinese credit card is mandatory. The bottom line: accessing the software is incredibly difficult.
Getting your hands on these titles is difficult and while we've been very keen on testing Shield's Wii emulator for months now, it's been a long road getting to this point and it requires having friends in China to do a lot of the heavy lifting for you. The rewards are worth it though. Loading up the game sees a license validation check followed by a Nintendo splash screen, followed by the first curiosity - an Nvidia Lightspeed Studios logo. Lightspeed works primarily on Shield's Android ports, which range from great (Doom 3 BFG Edition) to the not-so-impressive with a range of PC ports on the Shield portal that have fallen short of the standards set by the last-gen consoles. With the logos vanishing from view, Super Mario Galaxy kicks off, looking richer and more detailed than any prior Nintendo release of the game.
Based on the Shield marketing, we're promised 1080p versions of the Wii classics - but the truth is rather more fascinating. Based on our tests, Nintendo and Nvidia's emulation work has a lot in common with Xbox One X's enhancement of Xbox 360 games, in that Super Mario Galaxy benefits from a 3x increase in resolution on the X and Y axis, resulting in a 9x boost to pixel count overall. That yields a curious 1920x1404 resolution - a 30 per cent boost over standard 1080p that's downscaled to the display output. It's a curious state of affairs, but almost certainly down to the fact that Wii games usually operate at around 640x480, with the emulator stretching out the horizontal resolution for widescreen support. The emulator effectively works in reverse, running natively on the X axis and downscaling the vertical instead. There are other aspects of the presentation worthy of comment too.
