If you’re interested in emulation, then the Steam Deck is worth your whole. There’s a program called Emudeck that will set you up with all the emulators from Game Boy to PS2 (and more). It’s easy to download and run and will do a lot of the configuration for you. While I haven’t played any PS2 games on it yet, I have played GameCube games and they run just fine, and most of the older systems will also run well.
I think that was more collateral damage than anything, as Nintendo hasn’t went after clones of Citra the 3DS emulator like they have with clones of the switch emulator.
