AetherSX2 is one of the most popular PlayStation 2 (PS2) emulators for Android devices. It allows gamers to play their favorite PS2 games on mobile with smooth performance and high compatibility. However, to use AetherSX2 effectively, you need to set up a BIOS file, which is essential for running PS2 games on the emulator. In this guide, we’ll explain what the AetherSX2 BIOS is, where to download it safely, and how to set it up step by step.
What is AetherSX2 BIOS?
A BIOS (Basic Input/Output System) is a firmware file that helps the emulator replicate the functions of a real PlayStation 2 console. Without a BIOS file, AetherSX2 cannot run PS2 games properly because the emulator requires it to process game data and execute instructions.
There are different versions of PS2 BIOS files based on regions such as USA, Europe, and Japan. Selecting the correct BIOS version improves game compatibility and performance.
Is It Legal to Download AetherSX2 BIOS?
Before downloading a BIOS file, it’s important to understand the legal aspects. BIOS files are copyrighted by Sony, which means downloading them from unofficial sources is illegal. However, if you own a PS2 console, you can legally dump (extract) the BIOS from your device using special tools. Many gamers choose this method to stay within legal boundaries.

Method 1: Extract BIOS from Your PS2 Console
- Download a BIOS dumping tool such as PS2 Dumper on your PC.
- Copy the dumper file to a USB flash drive.
