It’s worth pointing out that the Series X can use retroarch (no hacks, just an app) which means you can play most PS2 games on it, in fact you can play PS1, GameCube, Super Nintendo, arcade, basically almost anything up to about the PS2 but there is starting to be some compatibility with PS3 so perhaps they will have that worked out at some point in the future. This option doesn’t give you games on a shelf though but does let you play more games than any console in history. Look up recent guides on YouTube
