The problem is that the DMCA is a flawed piece of legislature that hamstrings fair use in a couple of really key ways.
Obligatory IANAL, but my read on the (admittedly very legalese) section 1201 (https://www.law.cornell.edu/uscode/text/17/1201) is that it lists a very few exemptions for what is allowable under the DMCA with regard to bypassing copyright protection mechanisms, and archival copies of personal media are not in that list of exemptions. Archival use of computer programs is covered under section 117 (https://www.law.cornell.edu/uscode/text/17/117) and it allows you to make a bit-by-bit copy of your media for archiving it. It doesn’t allow you to bypass copyright protection mechanisms on that exist that content.
So, you’d be protected if you were making a 1:1 exact cloned (and therefore, encrypted) copy of your switch game. Any action to decrypt that switch game (because the encryption is explicitly a copyright protection mechanism) would be a violation, whether it be you doing it manually with a tool, or an emulator doing it on your behalf. If you move that violation outside of the emulator, I would think that based on how the law is written they’d have to find some other way you were violating the DMCA with the emulator specifically in order to target it.
Ultimately, I think the reason it’s illegal is because the DMCA is corpo crap that has been bastardized several times over to reduce consumer rights, but the lawyers seem to wield section 1201 as the silver bullet.
