HOW TO DOWNLOAD AND CONFIGURE EPSXE EMULATOR

Use Plug-Ins

Before you set up BIOS in this emulator to play PS games, you have to use some plug-ins with this emulator. Both DuckStation and RetroArch are advanced emulators with everything built in, so we don’t need to download or set up any plug-ins separately.
ePSXe is an outdated emulator and hasn’t been updated since 2016. So, to control different gaming aspects like graphics, sound, and reading game discs, we have to set plug-ins to get the best quality while playing PS games.

Here’s a quick breakdown of the most important plug-ins that you need with this emulator:

cdrPeops.dll: This is for CD-ROM support but isn’t necessary anymore.
DFSound.dll: This is the best audio plug-in, recommended for clear sound.
gpuPeopsSoft: A video plug-in for older computers.
gpuPeteD3D.dll, gpuPeteOpenGL.dll, gpuPeOpsOpenGL.dll: These are the best plug-ins for rendering 3D graphics, with Pete’s OpenGL being the top choice.
spuEternal.dll: A good audio plug-in for slower computers.

Configuring the BIOS in ePSXe

Go to Config > Bios.
In the Config Bios window, click the Select button.
gpuPeopsSoft: A video plug-in for older computers.
A new window will pop up. Find and select Scph1001.bin (the PS1 BIOS file).
Click Open.
Finally, click OK in the Config Bios window to save the settings.

Configuring Plug-Ins in ePSXe

Here is how you will configure audio and video plug-ins in the ePSxe emulator.

Configuring Video (Graphics)

Go to Config > Plugins > Video.
In the “Config Video” window, click the drop-down under Select/Config Main Video plug-in.
Choose P.E.Op.S. OpenGL Driver, This is the best one for compatibility.
Click on Configure below it.
In the new window, click Nice, then click OK.
In the “Config Video” window, click OK again.

Configuring Audio (Sound):

Go to Config > Plugins > Sound.
In the “Config Sound” window, click the drop-down under Select Sound plug-in.
Choose DirectSound Driver. This is the default, but if you have an older PC, you can try Eternal SPU instead.
Click on Configure below it.
In the configuration window, go to General Settings> Mode.
Change it from using SPUasync, which causes poor audio to High compatibility mode.
Click OK.

How To Download PS1 BIOS?

Then, place the BIOS file into the correct folder within the emulator’s installation directory. For DuckStation and ePSXe, move the file into the bios folder, while for RetroArch, place it in the system folder.
If the BIOS file is in the right location, most emulators will automatically detect it. For safety, you can go into the emulator’s settings to ensure it’s set up correctly for use.
Now that you’ve set up the PlayStation emulator and added the correct SCPH1001.bin, you can start playing PS1 ROM games.
