Play all of your favorite PS 1 games on your computer using ePSXe Emulator.
Remember Final Fantasy VIII? Remember Eden, Bahamuth, Shiva?? Or Suikoden II, Parasite Eve, Lunar, Rayman, Hercules, Xenogears?? Those where old, good times. Ever wish to play those games all over again or maybe finish them for the first time? You can install and run the necessary software to turn your PC into a virtual PlayStation. Today there are a lot of tutorials on the net about how to download and play PlayStation 1 games on your computer. The bad thing is that only few of the tutorials are really working and the others are not completely 
finished or aren't explained good and you can't understand them. Here i'll write a full tutorial to run PSX games on your computer. I will be posting links where to get emulator, ISOs and more!
Lets start:
1. Download ePSXe (PS1 emulator)
First of all you need to Download ePSXe. Here you can download ePSXe emulator for Linux and Windows. I recommend you to download version v.1.6.0 or lower (don't download any beta version).
2. Download plugins
Plugins will be necessary. You can download plugins for both OS, Windows and Linux. There are three plugins you basically need to run the program.
Go to http://www.ngemu.com/psx/epsxe.php?action=plugins and then press Ctrl+F and download the following plugins:
Graphic Plugins:
P.E.Op.S. Soft GPU (v1.18b)
Pete's GPU Plugins (v1.77)
Sound Plugins:
Eternal SPU (v1.41)
P.E.Op.S. DSound (v1.9)
CD Plugins (To make Game Rips such as ISOs and CDs run on ePSXe):
CDR Mooby (v2.8)
P.E.Op.S. CDR (v1.4)
You can also download Misc Plugins which allows you to play over the net, but those aren't necessary.
Extract the files into the "plugins" folder in the ePSXe. (It's NOT in C://Program Files...! Remember the path when you download the ePSXe program in the first place? And you double click on it to run it? Go there and you will find the "plugins" folder)
3. Download BIOS
Now it's time to get the BIOS in order to play the games. You'll need a file called scph1001.dll. Here is a website where you can download your BIOS http://dragonballarena.gamesurf.it/english/media/giochi/psx.php.
After the download is complete, place it on the "bios" folder in the ePSXe.
4. Download your game!!
You can type your game on google and search for it, or get torrent on isohunt, mininova or anything... Here are some good sites to download your PSX ISOs:

http://www.romulation.net/PSX/

http://nitroroms.com/roms/Sony_PSX

5. Configuration
Before you start using ePSXe you need to configure some settings. Select the icon that looks like a PSX controller ( that's the emulator itself ) and a window that says ePSXe should pop up. Now choose the Config tab and you are ready to configure the plugins and the bios that you've downloaded.
Config - Video
- Choose the plugin that you want to use. I use Pete's DX6 D3D Driver. Now choose Configure
- Choose the resolution, or whether you want to play it in a window. If you are wondering if the resolution depends on your computer performance... I personally choose window. Now on Default Settings (bottom-left) click Nice and OK.
Config - Sound
- Choose the plugin. I use P.E.Op.S. DSound Audio Driver -> Configure
- Choose following options:
Volume : 1
Reverb : 2
Interpolation: 3
Leave the rest as default and OK.
Config - Cdrom
- Choose the plugin. I use P.E.Op.S. CDR Driver
- Don't need to configure anything there.. leave it as default.
Config - Bios
- Locate the scph1001.dll and click OK
Config - Game Pad - Pad 1
- Adjust it at your convenience...
Now your all set and you can start playing some PSX Games!!!
File - Run ISO and Locate the PS1 game you want to play. If in the folder that you've downloaded there are more than one file, choose the one with the bigger size.
Enjoy Gaming!
If you don't want to spend much of your precious time, searching for plugins, bios and all other necessary stuff, you can download my ePSXe with all these stuff in it. Now all you have to do is just to configure the settings and you are ready to play.
