How To:

Quote:

1. Place the Official Sony Update (pbp) in the root of your ms.

2. Install RSPsar Dumper v3.0 (check the readme for install instructions, if it doesn't work after you installed it then refer back to the readme).

3. Confirm that your kernel is set to your currect firmware version.

4. Launch and decrypt all with SQUARE.

5. Acquire vshmain.prx from the location on your ms:
ms0:/Dump/F0/vsh/module/

*Highly Recommend* Rename the decrypted vshmain.prx to something other than it's original name, and place it on your Desktop.

6. Connect your flash0 to usb.

7. *MUST* Acquire vshmain.prx backup from the location on your flash0:
flash0:/vsh/module

Place this on your Desktop, and remember, this is your back up of the only file in danger.

8. From the Desktop, right click the decrypted vshmain.prx and select "Hex Edit with Hex Workshop v5.0"

9. Right click anywhere in the center box.

10. Make sure it's on Text String.

11. Type in the value "flash0" and click ok.

12. Check all of the Results in the bottom right box...

...until you come across the file-paths of the files you wish to relocate to flash1, flash2, or ms0.

13. Change flash0 in the right box...

...to flash1, flash2, or ms0.

14. Click "File" and "Save As" to get your modified vshmain.prx
MAKE SURE YOU MADE A BACKUP OF YOUR ORIGINAL vshmain.prx (step 7)

Put your modified vshmain.prx in:
flash0:/vsh/module/

15. Cut & Paste the files of the file-paths you changed to your Desktop and connect flash1, flash2, or ms0, whichever you selected, to usb.

16. Create the file structure in which the file you're moving originated (or to resemble the custom file path if you decided to make one) in the drive you chose to relocate the files to. Drop the files off of your Desktop into their corresponding folders.

17. Reboot your PSP. All should be well.

18. In the event something does not work:

A. Replace the modified vshmain.prx via Recovery Mode at flash0:/vsh/module/ with the backup vshmain.prx from your desktop.

B. Return the moved files to their original folders.

9) DONE! if you meet every step of this guide, you will have 4-6, possibly 7mb free on your flash0 WITH 1.50 kernel subset installed.
on slims, the freespace numbers may get pretty big please report them if you try it.
