BIOS files play a vital role in PlayStation 2 emulators by emulating the core functionalities of the console’s original firmware. They are responsible for crucial operations like hardware initialization, game loading, and system management. Without a BIOS, an emulator cannot operate effectively, as these processes are essential for running PS2 games with accuracy and efficiency.
