In case this was asked in earnest, yes- it happens all the time. Nintendo releases have been notoriously leaky for about 3 years now

There’s going to come a day where China releases some statement along the lines of “The United States continues to agitate against our development, but at what cost?” and it’s going to be the happiest day of my life.

If it’s early release it’s a warehouse leak most likely that then gets dumped from a modded console (xci format). Some users convert xci to nsp for reasons unknown to me. Might be that switch cartridges have extra padding at the beginning/end that can be stripped to reduce file size.

Otherwise it’s just a standard dump from a modded console in either eShop (nsp) or physical (xci) format

A couple of options worth knowing about since I don’t know/own the games:

1. A DRM free version looks like it’s available at GOG. This is probably the simplest solution to not have to worry about any potential issues
2. People seem to be reporting that the Steam version can be launched directly from the executable bypassing the launcher. If there is a Steamworks DRM check you could always use Goldberg’s steam emulator to get around that for fully offline play.
