When the Nintendo Switch launched in 2017, its custom NVIDIA Tegra X1 chip was already pretty outdated. Over the past eight years, many Android and x86 gaming handhelds offer more than enough horsepower to emulate even the most graphically intensive Switch games thanks to the likes of Ryujinx and Yuzu. But after years of mostly being quiet, Nintendo went on a DMCA spree last year, taking down the best Switch emulators, and now we know why.
Following the Nintendo Switch 2 Direct, the company published a series of articles and videos titled “Ask the Developers.” As it turns out, Nintendo is doing the exact thing that it’s trying to stop everyone else from doing — well, not exactly the same thing, but pretty darn close.
In one of the interviews published, Nintendo’s Kouichi Kawamoto and Takuirho Dohta were asked about backward compatibility with original Switch games. This might seem like an odd question, but it’s because the Switch 2 is reliant upon a completely different architecture compared to its predecessor. As a result, it’s not exactly as simple as taking your original Breath of the Wild cartridge, putting it in the Switch 2, and start playing.
When asked, “Does that mean the Switch and Switch 2 aren’t compatible at a hardware level?” Dohta responded, “If we tried to use technology like software emulators, we’d have to run Switch 2 at full capacity, but that would mean the battery wouldn’t last so long, so we did something that’s somewhere in between a software emulator and hardware compatibility.”
Reading between the lines a bit, it sounds to me like Nintendo wanted to just use an emulator to run Switch 1 games on the Switch 2. However, there isn’t enough power in the upcoming NVIDIA chip to allow for that without severely sacrificing battery life. It’s a common problem with Android and x86 handhelds as newer consoles just chew through battery like there’s no tomorrow.
To combat this problem, Nintendo took a slightly different approach, introducing something like a translation layer to relieve some of the pressure. This isn’t unheard of, as Apple’s M-series processors rely on Rosetta, and just last year, Microsoft introduced its Prism layer to accompany the Snapdragon Arm chips found in the latest Surface Laptop and Surface Pro models.
However, there’s another layer (pun intended) to how we’re going to be able to play Switch 2 games, and I have a feeling it’s Nintendo’s way of trying to prevent, or at least slow down, Switch 2 emulation.
