PS1 Bios Download (OFFICIAL) for DuckStation, RetroSrch & ePSXe Emulators
Download the official PS1 BIOS file to play classic PlayStation 1 games on emulators like DuckStation, RetroArch, and ePSXe. It helps your games run better and fixes loading issues. Use it on Windows, macOS, Linux, or Android to enjoy smooth and full PS1 game support.
Setting up a PlayStation 1 emulator like DuckStation, RetroArch, or ePSXe feels exciting until you get the “No BIOS Found” message. This error means your PS1 games won’t start on platforms like Windows, Android, macOS, or Linux. The fix? You need a working PS1 BIOS file.
The PS1 BIOS is the original startup software from Sony PlayStation 1. It helps your emulator act like a real console, so games can load and run properly. Without it, even the best emulator won’t work right.
What is PS1 BIOS?
The PS1 BIOS (Basic Input Output System) is the official startup firmware used by the original Sony PlayStation 1 console. It helps the system boot up, load games, and handle core functions. When using emulators like DuckStation, RetroArch, or ePSXe, the PS1 BIOS is needed to recreate that same startup process on modern devices.
Without the BIOS file, most PlayStation 1 emulators can’t run games properly. You may see errors like “No BIOS Found,” or experience crashes, missing audio, or loading issues. The BIOS ensures your PS1 game ISOs work smoothly, with full support for memory cards, save states, and compatibility.
This file doesn’t come built-in with emulators for legal reasons, so users must add it manually. Once installed, the BIOS unlocks full functionality, letting you enjoy classic PS1 games on Windows, macOS, Linux, or Android just like on the original console.

Types of PS1 BIOS Based on Region
When using a PlayStation 1 emulator like ePSXe, DuckStation, or RetroArch, choosing the right BIOS file based on region improves game performance and compatibility. BIOS files are specific to the region of the original Sony PlayStation console. Some emulators let you use multiple BIOS versions to cover different game formats. Here are the most common types:
🇺🇸 SCPH1001.BIN (North America – NTSC-U)
This is the most popular PS1 BIOS for U.S. and Canadian games. It’s known for excellent compatibility with NTSC-U titles and works smoothly on almost all major emulators. If you’re emulating games from North America, SCPH1001.BIN is the go-to choice.
🇪🇺 SCPH7502.BIN (Europe – PAL)
Used for PAL region games from Europe, SCPH7502.BIN supports unique PAL video formats and screen refresh rates. This BIOS ensures correct video output, language options, and sync for titles released in the UK, Germany, France, and other European countries.
🇯🇵 SCPH5500.BIN (Japan – NTSC-J)
This BIOS is designed for Japanese PlayStation games, including JRPGs, visual novels, and imports. SCPH5500.BIN ensures accurate text rendering, audio, and gameplay performance for NTSC-J titles.
🌍 SCPH7003.BIN (Multi-Region)
SCPH7003.BIN is a more flexible BIOS that supports multiple game regions. It’s ideal for users who play both NTSC and PAL titles without switching BIOS files. It offers solid compatibility across regions.
Using the correct BIOS helps your PS1 emulator run games the way they were meant to be played.
