When dumping a PlayStation BIOS, the resulting binary file is traditionally named scph5500.bin, scph5501.bin, or scph5502.bin following the Redump.org naming convention. The .bin extension signifies a raw binary dump of the 512KB (later 1MB on some models) ROM chip. A correct dump has a specific CRC32 and MD5 hash. For the SCPH-5500 V30, the most quoted hashes are: The SCPH-5500 BIOS is classified as a Version 3
