This is so wild.
I know that Wii U emulation got very far in short amounts of time, because its very similar to the Wii. But from my recollection the only big game that could be emulated well almost day and date with release was Breath of the Wild.
3DS emulation is largely the same story. Took a while to see results that outpaced legit hardware, although its longer life meant a lot of the later games were being emulated quite quickly.
And here we are with the Switch. Emulation can outperform native hardware that isn't on the cusp of being replaced. Its truly amazing work
