PSX BIOS Dumping guide

[Shendo]

Required hardware:

• Console capable of booting burned cds.
• PlayStation Memory Card.
• PlayStation Memory Card reader or a DexDrive.
• Cd-Writter.
• Blank Cd-R.

Required Software:

• BIOS dumper (attached).
• BIOS merge application (attached).
• Program to transfer saves from Memory Card to a PC:
  • Memory Card Captor Sakura (for Memory Card reader).
  • DexPlorer (for DexDrive).

Getting started:
The first thing that you need to do is to burn the BIOS dumper (psx.exe) to a Cd-R.
I used Nero but any burning software should do the trick.

If you have a chipped PSX you will have to download a program called BladeLib App Launcher.
If you use a PSX Boot Cd the launcher is not required.

Warning: Before you start dumping make sure that your Memory Card is completely blank,
otherwise BIOS segments may not dump properly.

Booting a dumper:
Put the dumper disc you burned earlier in your PSX and start it.

After a while a menu should show up.


From there you can choose which segment of the BIOS you want to dump.
To start dumping press X.

Dumping usually takes a minute so be patient.
Once it's done you should get a blue screen telling you to reset the console.



After a reset go to the Memory Card screen.
You should see 15 saves with the name "BIOS DUMP".


Transfer saves to PC:

PlayStation MemoryCard reader method:
Connect a memory card to your PC and open the Memory Card Captor Sakura.
Important: Make sure that you install the UserPort driver you got with the software.


Press "SLOT 1" to read the Memory Card data.
Now press "IMG R" and save the card with the .mcr extension and name it after a part you dumped (eg "Part1.mcr").

DexDrive method:
When you save a card use either a PSXMemtool or MemcardRex to convert .gme to .mcr.
Name each card after a part you dumped (eg "Part1.mcr").

Dump the other parts:
When it's done disconnect a Memory Card, connect it to PlayStation and delete the BIOS DUMP saves.
Repeat the steps above for the other four remaining parts.

Merging a BIOS:
Unpack the BIOS merge application and put it in some directory.
In that directory make a new directory called "Parts" and put all parts(.mcr files) there.
Run the "BIOS merge.exe" and press Merge.
You should get a file named SCPHXXXX.bin.

Look at the bottom of your console to get the model number (mine is SCPH-9002).


Rename the SCPHXXXX.bin to match your PlayStation model number.

Now run the PlayStation emulator of your choice to check if the BIOS is working.


If it's working then congratulations, you successfully dumped your PlayStation BIOS.
