You need to be able to successfully hack a Switch to even dump the games, which isn't easy and risks bricking the system. If you want Nintendo exclusives, you need Nintendo consoles. If you already have a PC, then you can already play all of the same games you would play on a Steam Deck. The Switch 2 has it's own games.
1. First off, it hasn’t been hacked to any use practical level. It only allows custom code execution. You can’t add custom firmware or modify the kernel. 2. Even if that were the case, why don’t you just use the Switch 2 to emulate all of the games you want as well as play switch 2 exclusives and the many 3rd party games coming to the system?
