Setting up ePSXe 1.9.0 remains a classic choice for retro gaming, though as of 2021, newer versions like 2.0.5 or modern alternatives like DuckStation have largely superseded it in terms of accuracy and features. If you are sticking with version 1.9.0 for its specific compatibility or "low-spec" friendly performance, here is how to configure it for the best results. 1. Essential BIOS Files
A BIOS (Basic Input/Output System) is the "soul" of the original PlayStation hardware and is required for full compatibility. While ePSXe 1.9.25 and later introduced a High-Level Emulation (HLE) BIOS, an official BIOS file is still recommended for the most stable experience.
Recommended File: SCPH1001.bin (North American) is widely considered the most stable.
Installation: Place your BIOS file into the /bios folder located within your ePSXe directory.
Configuration: Open ePSXe, go to Config > Bios, click Select, and navigate to your SCPH1001.bin file. 2. Best-in-Class Plugins
The ePSXe 1.9.0 remains a cornerstone of PlayStation 1 (PS1) emulation, prized for its high compatibility and iconic plugin system. While newer versions like 2.0.5 and competitors like DuckStation have emerged, many users in 2021 and beyond still prefer 1.9.0 for its stability on older hardware or "potatoes".

Common Version: SCPH1001.bin (US) or SCPH7502.bin (European) are highly recommended for the best compatibility.
The Plugins: Unlike modern emulators that are "all-in-one," ePSXe uses separate software modules to handle graphics, sound, and CD-ROM reading. Top Recommendations for 2021 Setup Setting up ePSXe 1
