What is PS2 BIOS?
The PS2 BIOS is a crucial component that serves as the primary bridge between hardware and software (games). The PS2 BIOS is the first program executed to initialize the system, configure the memory card, and display the PS2's signature startup animation. In the emulator workflow, the BIOS file is essential for emulators like PCSX2, ArmSX2, and AetherSX2 to accurately mimic the workings of a PlayStation 2 console. Without the crucial instructions from the BIOS, an emulator is simply a useless application and cannot run your favorite PS2 game discs.
PS2 BIOS Features
Startup & Initialization
Displays the typical PlayStation 2 boot animation and starts all system components. This process will tell the emulator that the PS2 BIOS is ready to run your PS2 game disc.
Memory Card Management
The BIOS can manage data such as viewing, copying, or deleting files on the virtual Memory Card. This feature is very useful for keeping your game progress safe and allowing you to reload it.
Console Settings Menu
Has basic control center access to adjust various system settings such as date, time, language, and audio/video output to suit your device.
PlayStation 1 Support
Also supports running PlayStation 1 (PS1) games, with better improvements and optimizations compared to the original PS1 BIOS.
Integrated Media Player
It can also play music CDs and video DVDs, which is very useful for multimedia needs. BIOS is not only used for playing games but also as a media player.
Error Handling & Diagnostics
Able to detect if an error is detected and will display an error message, such as "Red Screen of Death" as a marker, this can help find problems in game files or in emulator applications.
Disc Security & Authentication
Uses a secure authentication process to verify the authenticity of the game disc. This is a security system designed by Sony to protect against piracy.
Input & Accessory Management
Manages all connected hardware such as gamepad controllers, memory cards, and other external accessories, and it is also useful for ensuring everything is connected to the PS2 system perfectly.
Differences Between NTSC and PAL PS2 BIOS
PS2 BIOS NTSC and PAL are two BIOS versions that you need to understand before downloading the PS2 BIOS that we provide, NTSC and PAL are screen color coding used by PS2 BIOS. This coding variant depends on the geographic region and electrical current where the bios is released.
NTSC (National Television System Committee)
NTSC is the standard used principally in North America (USA, Canada, Mexico), parts of South America, and Japan. This is based on a 60 Hz power grid frequency.
PAL (Phase Alternating Line)
PAL is a standard used by most countries in Europe, Australia, Africa, and Asia, including Indonesia. This runs on a 50 Hz power grid frequency.
Effect on Emulators
This difference in power frequency makes technical differences in the video output, which directly affects the gaming experience on emulators such as AetherSX2 and PCSX2.
Difference in Refresh Rate on NTSC and PAL
The difference in refresh rate will be very noticeable when playing the PS2 Emulator, here are some of the differences:
- PS2 BIOS NTSC: Displays a 60 Hz Refresh Rate on your screen. This will produce a Refresh Rate image of 60 times per second.
- PS2 BIOS PAL : Displays a Refresh Rate speed of 50 Hz, this means it will display a refresh rate image of 50 times per second. PAL can be said to be targeted for 50 FPS only. which is suitable for the European region.
Notes: The NTSC version of the PS2 GAME will feel faster and smoother than the PAL version. The difference is quite significant, around 17%. Many games that were originally developed in Japan or the US (NTSC region) were then ported to the PAL market. If the developer does not optimize the game properly, the PAL version of the game will run slower than it should, a phenomenon known as "PAL slowdown".
Vertical Resolution and Image Display Differences
The second difference lies in the number of horizontal lines that make up the image on the screen.
- PS2 BIOS NTSC : uses a standard resolution of 480i (480 interlaced horizontal lines).
- PS2 BIOS PAL : Uses a standard resolution of 576i (576 interlaced horizontal lines).
Note: the higher resolution of PAL (having 96 more lines) should produce a slightly sharper and more detailed image. However, in practice, many NTSC game developers do not adjust the aspect ratio of their games when porting to PAL. As a result, in order to fill the 576i screen without destroying the image proportions, they added thick black lines at the top and bottom of the screen (letterboxing). This is known as "PAL borders" which actually reduces the effective image area.
Supported Emulators
PCSX2
PCSX2 is the original and most mature open-source PlayStation 2 emulator, celebrated for its high game compatibility and extensive configuration options.

Although its development is paused, it remains highly functional. AetherSX2 also requires a PS2 BIOS file to play games.
ArmSX2
ArmSX2 is a new PS2 emulator based on PCSX2, designed for devices with the Arm64 architecture and supporting Android and iOS operating systems. It's an alternative to AetherSX2, whose development has long been discontinued. The PS2 BIOS we provide fully supports the ArmSX2 emulator and we've tested it ourselves.
