Updating psp from usb connection
An excellent program for Multi-Display setups is "Ultra Mon".
It also works a charm for this setup, so I recommend you try it out.
So, how does one exactly unleash the power of this pint-sized monster from Sony?
Just click "have disk".6] Now, browse to X:\%PSPDisp Install Directory%\bin\driver_display. Just follow the rest of the instructions the Wizard gives you!
Run the installer and go to the install directory afterwards (eg. Go into the "bin" folder, and then to psp\PSP\GAME.
Copy the PSPDisp folder to the PSP\GAME folder on your PSP's memory stick.
It can extend the taskbar to the second desktop, change wallpapers of desktops respectively, and more.
It's a trial version, though and costs .95 for a licence.
