Downgrading 2.00 -> 1.50 method
-------------------------------

Requires :
----------

- PSP 2.00 (if you have an 1.51 or 1.52, update to 2.00)
- The 1.50 EBOOT.PBP update (http://shockzone.free.fr/PSP/Tool/EBOOT_1.50.zip)
- MPHDowngrader (http://www.chez.com/mph/)

Installation :
--------------

- Create a UPDATE folder in PSP/GAME/ folder of your memory stick
- Copy EBOOT.PBP (update 1.50) in UPDATE folder
- Unpack MPHDowngrader.zip
- Copy overflow.tif in your PSP/PHOTO/ folder of your memory stick
- Copy h.bin in root of your memory stick
- Copy index.dat in root of your memory stick
- Plug the AC adaptor

Then, enter in VSHELL PHOTO MENU, this will launch Version Changer.

Create an USB connection and if the Version Changer has been installed, a new file is created in your root of your memory stick (ms0:/index.dat.bak).

Then go to VSHELL GAME MENU and launch 1.50 update.

Follow the instructions ...
