This article provides information on setting up the Sony PlayStation emulator ePSXe.
This guide is for ePSXe 1.7.0.


Begin by unzipping the file into it's appropriate folder.
If the emulator will be used within Maximus Arcade the folder should be:
C:\Maximus Arcade\Emulators\epsxe170


Make sure that the zlib1.dll is located in the same folder as the ePSXe.exe file. The zlib1.dll is not included in the ePSXe 1.7.0 download mentioned above, it must be obtained from somewhere else. If it is not located there you will receive the following error:
You can download the zlib1.dll here:

BIOS files

ePSXe requires a valid PlayStaion BIOS file. It is recommended to use one of the following versions:
  • SCPH1001.BIN
  • SCPH7502.BIN
Copy one or both of the above mentioned BIOS files into the following folder:

Setup Wizard

When you start ePSXe for the first time you will be prompted with the ePSXe Config Setup wizard. You can go through the wizard now or choose Skip Config. You can access the wizard at any time through the Config > Wizard Guide menu item. The wizard has 7 setup pages including the initial welcome page and the final configured page.


Select the BIOS you would like to use for the emulator. It is recommended you use either the SCPH-1001 or the SCPH-7502.
You will not be able to proceed to the next step in the setup wizard if you do not have any BIOS present in the folder:


Select the GPU plugin for rendering video on this page. If there are no GPU plugins found in the plugins folder a warning dialog will be shown and you will not be able to proceed any further in the setup process.
The plugins folder is:
Pete's OpenGL2 Driver 2.9 is the recommended video plugin.


Make sure you have the video plugin copied to the \epsxe170\plugins folder.
  1. Select Pete's OpenGL2 Driver 2.9 in the list box.
  2. Click the Test button to test that the plugin is working correctly.
  3. Click the Config button to configure the plugin.

The video plugin's configure window should look similar to the image below:


Shaders help strengthen colors, anti-alias the image, and add a nice blur that hides numerous PS1 visual flaws which high resolutions will not heal alone.
Shaders should be placed in the following folder:
Below is a list of some popular shaders and their primary effects on the video:
  • ShadX's Natural Vision Shader - Intensifies colors/makes them more vibrant than normal as well as gives an anti-aliased look
  • SimoneT's Bump Map Shader - Produces a nice bump effect/glass look
  • Luigi's "Blur AA" shader - Provides a fullscreen smoothing effect
  • Guest's Shader Collection - Contains many custom shader files including both Cartoon Shader and StoryBook Shaders
To enable shaders make sure the Shader effects check box is check under the Fullscreen filters section in the video plugin's configuration window. In the drop down select the appropriate setting based on the shader plugin being used. Finally select the desired Shader level.
For the best results use the Natural shader with the settings shown below:
NOTE: In order to use shaders you should have a reasonably powerful graphics card. Typical onboard graphics will not be enough to use shaders and will cause the game to be slow.
