This guide will show you everything step by step. You will learn how to add the BIOS file, set it up inside DuckStation, and make sure it runs smoothly on macOS. The instructions are simple and clear so anyone can follow along.

By the end, you will have your favorite PS1 games running on your Mac with full sound and graphics. It will feel just like the classic PlayStation days. Grab your controller and get ready to relive the nostalgia.

Why Does the PS1 BIOS Matter?

The BIOS is the PlayStation’s system software. It makes the console start up and load games correctly. Without it, DuckStation on your Mac will not run any PS1 game.

When you place the BIOS file in the right folder, DuckStation can read it and act like the original PlayStation. This is what allows games to boot, menus to appear, and controls to respond as they should. If the BIOS is missing or the wrong version, you will only see errors or black screens.

How to Get the PS1 BIOS File (Legally and Safely)

To make DuckStation work properly, you need a valid PS1 BIOS file. This file acts as the console’s internal system, helping your Mac run PlayStation games the right way.

The best way is to dump the BIOS from your own PlayStation console. That keeps everything legal and safe. Some of the most common BIOS files you will see are named SCPH1001.bin, SCPH5500.bin, and SCPH7001.bin.

If you do not have the tools to dump your own, you can still get the BIOS online. You can easily download PS1 BIOS files from PS1Bios.online. Just go to the website and click the Download button, which will take you to the PS1 BIOS files page. Then scroll down and select the BIOS type you want to download for your emulator.
