This is not from a physical PS1 console. It is the BIOS file extracted from the official Sony PSP (PlayStation Portable) firmware 6.60.
As Sony refined the console, the internal software evolved. The comes from a later hardware revision (often colloquially associated with the SCPH-7000/7500 series internals in some regions, but distinct in version numbering).
Without a proper BIOS, many games will fail to boot or crash during gameplay. Frequently used as a reliable, stable alternative to
: Another BIOS file, potentially for a PS2 given the higher model number compared to the original PlayStation.

Modern emulators like DuckStation allow you to place all five .bin files in the same directory. The emulator will automatically select the correct one based on the game’s region.
: The firmware for the PS one (the smaller, redesigned white console). It features a revamped BIOS interface and is often the fallback for newer PS1 hardware emulations. Why You Need These Files Without a proper BIOS, many games will fail
