Map your keyboard or USB gamepad (like a PS3/PS4 controller) to the corresponding PS1 buttons. Setting Up Memory Cards (Saving Your Games)
BIOS: The Heart of Authenticity The BIOS (Basic Input/Output System) is central to any console emulator because it provides the low-level firmware routines used by original games. ePSXe requires a PS1 BIOS dump to boot games exactly as hardware would — from the manufacturer’s boot sequence to region checks and CD-ROM initialization. Using an official BIOS produces the highest fidelity in behavior and compatibility, reproducing console quirks and enabling some copy-protection mechanisms to behave as intended. However, because BIOS images are copyrighted and tied to physical consoles, legal and ethical use demands that users obtain a BIOS only from their own PS1 hardware. ePSXe’s reliance on the BIOS underscores a trade-off: fidelity and compatibility versus the legal constraints of using proprietary firmware.
