ePSXe

ePSXe is one of the best Playstation emulators out there. It can only emulate Playstation 1 games. The application can emulate every aspect of a Playstation 1 with incredible accuracy.

If you have original CDs for your games (copies should work too), ePSXe will play the full game, let you save in virtual memory cards, play sound and even let you use gamepads on your computer.

Emulating Playstation games does take a little of computing power, but modern computers shouldn't have a problem doing it. In my own testing, I was able to play a few games I had chosen without any problems. The video wasn't slow at all and full 3D games played smoothly at all times. There is a multiplayer feature called netplay, which supposedly allows you to play with other people, but I couldn't get it to work.

Installation and configuration is a big deal with emulators of this kind. I am sure that all PSX emulators suffer from this problem. However, I should tell you that you are not going to be able to play games after you installed the app. You have to get a variety of files from the Internet and copy them in certain directories of the emulator for it to even finish the configuration wizard. The process isn't hard if you are Google-friendly. A couple of searches should do the trick. However, dead links are making it harder and harder to get the files that you need as the years go by.
