Hey, guess what? That’s piracy!
You aren’t licensed to play that game on a PC or in an emulator. It doesn’t matter if you paid for the game and paid for the Nintendo Switch to play it on. If you used a hacked Switch to dump the console or you downloaded the rom, that’s piracy. It is not legal to circumvent the DMCA for fair use reasons.[1]
It is very cut and dried in the legal world, and it would take a very significant case and a few appeals which uphold a decision that changes how the DMCA is interpreted in the courts.
If you’re not in the US and not a US citizen, then I have no idea what laws apply to you or how they are interpreted.

I live in the EU, where consumers are authorized by Directive 2009/24/EC to reproduce and translate computer programs on other systems in order to achieve interoperability.
But even in the US there is the Sony v. Connectix precedent that creation of interoperable products is compliant with the DMCA and the anti-circumvention provisions do not apply to them.
