The PS2 BIOS is a crucial component for running PS2 emulation, connecting the hardware to the PS2 software system. Modern emulators like PCSX2, AetherSX2, and ArmSX2 require the PS2 BIOS to run PS2 games smoothly and at maximum performance.
The PS2 BIOS has various variants such as USA NTSC, EUROPA PAL, JAPAN NTSC, RUSSIA PAL, China NTSC, and Hong Kong/ASIA NTSC. Each of which must be appropriate for your region. For example, if you live in America, you must use the BIOS version for USA NTSC. If you are in another region, you can adjust it to suit your hardware.
