Nintendo Switch emulator, Yuzu, developers settling lawsuit from Nintendo with $2.4M payout, handing over its domains, and agreeing "Yuzu [is] primarily designed to circumvent [DRM]".
I own a launch era Switch. When I run Yuzu, I use the keys that I pulled off of it. When I play games in Yuzu, they are games I have purchased and dumped using the Switch Nintendo sold me. The controller I use is a Nintendo Pro controller. I play on my computer because it is MUCH better at playing Switch games than my overclocked Switch is. Just fuck off with this Nintendo, stop making your games worse.
Your Switch needs to be hackable. If yours is any revision beyond the initial release chances are you are out of luck. I set it up a long while ago so I can't recall the steps, but googling "Nintendo switch overclock" will get you what you're looking for.
The Switch is based on the Nvidia Shield, whose stock clocks are roughly double the Switch's. This means you can OC it without exceeding the manufacturer's specs, which is pretty neat. Bringing the memory clocks up really helps titles like ToTK.
It is dead simple, just make sure you get one of the little jobbies that you slide down the right joycon rail to short the pins that you need shorted - you'll be doing it often when you're setting things up and you don't want to be messing around with a bit of wire. I seriously doubt that you will brick anything, especially if you take your time and read everything through before you get started. These instructions should get you where you want to be.
