I'm not referring to homebrew emulators, I'm referring to official emulators made by the original console manufacturer.lmao what type of weed you smoking?
If XBOX 360 can be emulated perfectly on XBOX One, then the Switch can do it to. The Switch is only slightly less powerful.
If Wii can be emulated perfectly on the Tegra X1-based NVIDIA Shield TV, the Switch can do it too.
Gamecube same thing, as the Wii is just a higher-powered Gamecube.
If it can do Wii, it can do PS2, Dreamcast and XBOX no problem.
