Buenas,
He encontrado esto por ahí, en teoría basta con poner el overflow.tif en la carpeta /MUSIC en lugar de PHOTO pero...¿son tan tontos los de SONY???
Update to 2.1 Firmware download and extract the MPH Downgrader here:
http://www.emulation64.com/files/info/711/ read this tutorial on where to place the files: Steps to use the MPH downgrader:
- Create an UPDATE folder in the /PSP/GAME/ folder of your memory stick
- Copy EBOOT.PBP (update 1.50) in /PSP/GAME/UPDATE folder
- Unpack MPHDowngrader.zip
- Copy overflow.tif in your /PSP/PHOTO/ folder of your memory stick
- Copy h.bin to root of your memory stick (meaning in ms0:/)
- Copy index.dat in root of your memory stick (meaning in ms0:/ as well)
- Plug the AC adaptor
Then run the downgrader but dont forget to put the overflow.tif in PSP/MUSIC instead of PSP/PHOTO
Saludos,
Dumbis
