WHAT IS AETHERSX2 BIOS

A BIOS (Basic Input/Output System) is the small piece of software originally built into every PS2 console. It is essential for running AetherSX2 or any other emulator. Learn the difference between aethersx2 and pcx2 here
When you import the PS2 BIOS, it acts as the console’s brain, helping the emulator start games, read memory cards, and keep everything running as if you were using an actual PS2. Without downloading the BIOS, the emulator will not function, making it an important component for gaming.

So basically it isn’t the game itself but rather just the console’s system file. You’ll still need PS2 game ISOs to play the games on Aethersx2 .
