Every PlayStation console contains a BIOS (Basic Input/Output System)—a small chip with Sony’s copyrighted code that initializes the hardware and handles low-level functions like disc decryption and controller input. ePSXe cannot legally include a BIOS file. To run games, users must provide their own BIOS dump extracted from a physically owned PlayStation console. Common BIOS files include scph1001.bin (USA), scph7502.bin (Europe), and scph5500.bin (Japan).
