I am looking for a good Playstation emulator. I am really only interested in running Castlevania SOTN. I do own like 3 Playstations and 2 copies of the game so it should be all legal and stuff. I just want to play it on my PC because it's a bit easier for me.

I would like a Windows based emulator and something that won't take me much effort to learn to use.

Any advice is appreciated !!
