PSX Bios – Playstation PS1 Bios (SCPH1001.bin)

If you’ve ever tried to run a PS1 game on an emulator and it just didn’t work. Maybe it froze, gave you a black screen, or flat-out crashed, it’s probably because you were missing one small but crucial file: the BIOS. Specifically, the one called SCPH1001.bin.

Think of it like this: the BIOS is what helps your emulator behave like an actual PlayStation. Without it, the emulator is kind of blind. It doesn’t know how to boot things up properly, which is why games glitch out or fail to load.

You can grab the most reliable version of the PS1 BIOS right here. It’s safe, quick to set up, and makes a huge difference in how well your games run. No weird errors, no headaches.

So What’s in This File?

The file name is SCPH1001.bin it’s just under 1MB in size, and it works like a charm with emulators like ePSXe, RetroArch, DuckStation, and others. People sometimes call it the “PSX BIOS,” but it’s the same file.

Why You Actually Need the PS1 BIOS

Without this BIOS, your emulator is missing a key part of the puzzle. Some games might not even start. Others could freeze, stutter, or play without sound. Save features? They might not work at all. It’s kind of a gamble.

How to Use It (It’s Easy)

Download the file from this page. Then drop it into your emulator’s BIOS folder. After that, just go into the settings, select the BIOS, and restart the app. Done. Your emulator now behaves like a proper PlayStation.

Is SCPH1001.bin Safe to Use?

Yep. It’s been checked, tested, and used by tons of people without any issues. Just be sure to use it legally, you should own an actual PS1 console if you’re using this BIOS.
