Gaming corporations are doing their damnedest to get rid of emulation and piracy on top of getting rid of original versions of these games. Sure, we can re-download these things from piracy sites but keep in mind that these sites are constantly being attacked by copyright ghouls. Archive.org or your favourite rom or torrent site might not be around tomorrow. The internet is becoming increasingly corporate and restricted and it's important that these things not be lost to time and the only versions left are bastardised "remasters" locked behind a subscription to be ended anytime or until the next bastardised remaster comes along.
And if you're lucky enough to own a physical copy of a game, learn how to dump that shit onto a computer.
If you go the VPN route make sure you do a leak test(https://ipleak.net/) before you start downloading stuff. If you pass those tests you're safe.
You can definitely get PSX games from torrent sites, I just checked 1337.to and they've got a ton.
Real-debrid is cheaper and easier to setup safely for a beginner. It's basically just a service that downloads torrents(and those weird paid download sites like nitro upload) for you. You submit the torrent file or magnet link to their website and it gives you a direct download link. Since you aren't sharing pirated files with anyone, there's no chance of getting copyright warnings. There are also a bunch of streaming apps(stremio is the best) that work with real-debrid to give you a Netflix like experience for pirated movies/TV with little effort.
Thanks for the tips!
