What is PS2 BIOS?
The PlayStation 2 BIOS (Basic Input/Output System) is essential firmware that every PS2 emulator requires to function. It contains the core system software that initializes the virtual PlayStation 2 hardware, manages boot sequences, and provides critical system functions that games depend on.
Without authentic BIOS files, emulators like PCSX2 and AetherSX2 cannot boot or run PS2 games. The BIOS you choose should match the region of your games for optimal compatibility.
