The goal of emulation is to play games on other platforms. Preservation is a nice benefit.
If that doesn’t work without official permission then it doesn’t work at all. Fuck their bottom line. You have a right to culture, and a right to run software as you see fit.
I own a switch and a steam deck and I’ve bought my switch games. Nintendo is telling me I’m not allowed to run the games I legally purchased from them on my steam deck. Fuck 'em. Piracy isn’t a new thing, you don’t even need emulation to pirate games on the PC but PC gaming is thriving.
