File can be identified using offsets: 0x00000000: 13 00 08 3C 0x00000108 "Sony Computer Entertainment Inc."

NOTE:Not all BIOSes are loaded to 0xBFC00000. Check offset 0x70 as a 32-bit little endian unsigned int and do load addr = ((val << 2) & 0x3FFFF000). It's almost always going to give you a result of 0x1FC00000 but 0x1FA00000 is also known(for dev hardware).
