Step-by-Step Guide to Set Up ePSXe

Follow these steps to get ePSXe running smoothly on your PC in 2025.

Step 1: Download and install ePSXe

  1. Visit the Official Website: Go to ePSXe.com and download the latest version (e.g., ePSXe v2.0.5 for Windows).
  2. Extract the Files: Use WinRAR or 7-Zip to unzip the downloaded file to a folder (e.g., C:\ePSXe).
  3. Run ePSXe: Double-click ePSXe.exe. If prompted, install any required dependencies (e.g., DirectX).

Pro Tip: Avoid third-party download sites to prevent malware. Stick to the official source.

Step 2: Obtain and Configure the PS1 BIOS

The BIOS is essential for ePSXe to emulate the PS1 hardware. Here’s how to set it up:

  1. Acquire a BIOS File: Legally dump the BIOS from your own PS1 console (e.g., SCPH1001.bin for North America). We do not endorse downloading BIOS files from unauthorized sources.
  2. Place the BIOS: Copy the BIOS file to the bios folder in your ePSXe directory (e.g., C:\ePSXe\bios).
  3. Configure BIOS:
    • Open ePSXe and select Config > Bios.
    • Click Select and choose your BIOS file (e.g., SCPH1001.bin).
    • Click OK to save.

Step 3: Install Plugins for Graphics, Sound, and Input

ePSXe relies on plugins to handle graphics, sound, and controller input. In 2025, these are the best plugins:

  • Graphics Plugin: Pete’s OpenGL2 GPU (or P.E.Op.S. Soft GPU for low-end PCs).
    • Download from NGEmu or ePSXe’s plugin page.
    • Extract to C:\ePSXe\plugins.
    • Config: Config > Video > Select Plugin (e.g., Pete’s OpenGL2). Set resolution to 1280x720 or 1920x1080 for modern displays.
  • Sound Plugin: ePSXe SPU Core (default) or Eternal SPU for better audio.
    • Config: Config > Sound > Select Plugin. Enable “High Compatibility Mode.”
  • Input Plugin: ePSXe Input Core or LilyPad for advanced controller support.
    • Config: Config > Gamepad > Port 1. Map your USB controller to PS1 buttons.
