The ps1_rom.bin file is a universal PlayStation 1 BIOS file extracted from PlayStation 3 (PS3) firmware. It is widely used in emulation because it is compatible with games from all regions (NTSC-U, NTSC-J, and PAL), making it a popular "all-in-one" alternative to region-specific BIOS files like scph1001.bin (US) or scph5500.bin (JP).

Abstract:
The PlayStation 3’s hardware-emulated backwards compatibility remains a critical vector for analyzing legacy BIOS propagation. This paper examines a specific file artifact, Ps1-rom.bin, labeled under the context string -ps3 Ps1 Bios-. We investigate the cryptographic integrity, origin signatures, and hypervisor-level execution constraints of this BIOS image. Our findings indicate that while the file conforms to the standard 512 KB PS1 BIOS structure, the metadata tag -ps3 suggests a repackaged or region-modified variant intended to bypass Sony’s official ps1_rom.bin hash checks within Custom Firmware (CFW) environments.
