The BIOS (Basic Input/Output System) is the firmware that boots the console. It handles the boot logo, the CD player, memory card management, and libcrypt security. The SCPH-5502 shipped with BIOS version v3.0 (Europe) .
There is one primary reason: Emulation.
If you want to emulate PlayStation games on a PC (using DuckStation, ePSXe, RetroArch, or Xebra) or on a handheld device (Steam Deck, RG35XX, Anbernic devices), you legally need a BIOS file. Without a valid BIOS, most PlayStation emulators will either fail to boot or will use a slower, unofficial "HLE" (High Level Emulation) BIOS that has game compatibility issues.
Most later PS1 models used v4.x or v5.x BIOS. The v3.0 BIOS was exclusive to the 550x and 700x series. Here is the breakdown:
