The Parallel I/O port on the back of the console maps to memory address 0x1F000000. Valid ROMs can be identified with offsets:
0x00000004: "Licensed by Sony Computer Entertainment, Inc."
0x00000084: "Licensed by Sony Computer Entertainment, Inc."
By default, the BIOS creates a memory region of 0x1F000000-0x1F07FFFF for the PIO port but software can easily change the size anywhere between 1 and 0x00800000 bytes. I would suggest and "uninitialized" segment be used and 0x00800000 be the size.
Entry points will be the 32-bit addresses at offset 0x00000000 and 0x00000080. If value is NULL(0x00000000) that entry point wont be used.
