It's cool that this topic has come up, cause I've recently got into abandonware via SH2! Silent Hill 2 is very well-known as a game, but despite its notoriety, not a lot of people realize that playing the original game is nearly impossible without emulation--unless you already had a copy when it was in "print" (does that word apply to games?). Either way, since I never had any playstation consoles growing up, I had to download the preserved game files and run them with a mod to convince my computer that the CD/ROM drive wasn't empty. It took some time to figure out, but it runs as smoothly as my computer is physically capable of. The mod fixed some things that were missing from the original PC port as well. I'm very satisfied with the outcome so far.
I think one of the coolest things about it is that I can see the dev's files in my computer... it feels like archaeology to read through!
