How do I pirate the older titles?

So I'm gonna be blunt, I want to play the older games (1-4) and have found The Room on a reliable site but I cannot seem to track down 2, 3 or 1. 2's spin off title about Maria is out there but I cannot find anything. Even the old 2/3 HD remaster is gone from the PlayStation store, and 1 such a relic it doesn't even exist online. To the suprise of no one, the only Steam title other than 2 Remake is Homecoming, the literal worst game made other than book of memes. I also wouldn't mind playing Downpour, but I'm pretty sure you can get that on the Microsoft store and it's not high priority. Does anyone know any shady spots I can go to find a copy of these legendary titles?
