What is PS1 BIOS?
PS1 BIOS is a small program or bios file stored in the original PlayStation 1 console. It helps the console start up, load games, and manage basic tasks like saving and loading game data. The BIOS also checks if the game disc or file is valid and ensures it works properly with the system. It’s like the brain of the PlayStation that keeps everything running smoothly.
When using PS1 emulators on a computer to play PlayStation games, the BIOS file is essential. It acts as a bridge between the emulator and the games, making them work just like they would on the original console. However, sharing or downloading PS1 and PS2 BIOS files without owning the PlayStation is illegal in many places. That’s why I am giving you Official and legal PS BIOS files here.

PS1 BIOS Types Based on Region
PS1 Bios has different versions depending on regions. You have to install the same version of region to run Bios file smoothly in your device. If in case you want to use other region’s version then you have to be in that region physically.
Some Regional Versions of PS1 BIOS
SCPH1001.BIN (USA)
This is the BIOS for North American (USA) PlayStation consoles. It is one of the most commonly used BIOS files for PS1 emulators because it supports NTSC games. It is often recommended for general use in emulators like ePSXe, RetroArch, and DuckStation.
SCPH7502.BIN (Europe/PAL)
This BIOS is used for European (PAL) PlayStation consoles. It supports PAL region games and differs slightly from the NTSC BIOS, mainly in video output and frame rates. It is necessary for running PAL-region games correctly on an emulator.
SCPH5500.BIN (Japan)
This BIOS is used for Japanese (NTSC-J) PlayStation consoles. It is required for playing Japanese-region games on an emulator.
SCPH7003.BIN
This is another PlayStation BIOS used for different models and regions. It is less common than the others but can still be required for specific hardware or regional settings.
Each BIOS is region-specific and ensures the correct emulation of games by matching the video and system settings for the region.
Supported PS1 Emulators for Android, iOS and Windows
Here is the top five emulators for playing PS1 or PSP games.
1. ePSXe (PC & Android)
Number one is ePSXe. This is the best emulator for PS1 on PC. It was one of the first PS1 emulators to be released and is still the best. It has a large compatibility list, playing almost every game with no issue, and the gameplay is super smooth, meaning it’s fast and accurate.
Something super cool about this emulator is that you can also play original PS1 discs on your laptop or PC through the emulator. The only con with this emulator is once again you will have to provide your own BIOS.

2. DuckStation (PC & Android)
Number two is DuckStation, a great fully featured emulator. This emulator is very accurate and compatible with several hardware configurations. There is resolution upscaling all the way up to 8K, texture filtering, and widescreen hacks.
Something that I find really helpful is that DuckStation has automatic save states upon exiting your game, so you never have to worry about ditching your game save or not. Now, you will have to provide your own BIOS to get this emulator up and running, but when you do, it’s great.

3. RetroArch (PC, Android, iOS)
Number three is the emulator that continues to make all of my list videos, that being RetroArch. And just like for every other system, yes, it has PS1 cores that work very well. The core I use is called Beetle PSX and it gets the job done with quite a few features added on such as upscaling, texture filtering, save states, and rewind just to name a few.
But as always, if you are new to emulation, then getting PS1 set up with RetroArch may be a hassle to do.

4. PCSX Reloaded (PC)
Number four is PCSX Reloaded. It’s a nice clean emulator that is not complicated, with a nice clean interface to match. The compatibility is not as good as other emulators on this list and it won’t get any better because the emulator is no longer in development. But I will say for everything it does play, which is still a ton of games, the functionality and stability is great.
Also, one thing you will appreciate is that PCSX comes with a built-in BIOS file.

5. Xebra (PC & Android)
Number five is Xebra. It is a really easy emulator to set up which is always good for beginners, and it has a huge compatibility list meaning they can play almost every PS1 game out there. I would say it’s the best on this list.
What I don’t like about Xebra is there is no graphics upscaling available, but the reason it made the list is because it plays PS1 games perfect at their native resolution and for how simple it is to set up and use.
