| Q4: |
How
do I dump a PlayStation Bios? |
| A4: |
To
dump a PlayStation Bios, you need a GameShark or Action replay and a PC
comms link. To start, you need either a real Caetla module or go to AltaVista
and search for "Caetla" (it's a BIOS replacement for
your module, so read the included documentation properly before
installing it !!). Now upload "Caetla", and use use the caetla
commands for downloading a binary memory image from the region
0x0bfc00000 - 0x0bfc7ffff ! Now save the image as SCPHxxxx.bin, where
xxxx is your PSX's model number, and emulators will recognize it and use
it from now on. |
