PSP Firmware Dumper 1.0

Nem has released some code that will dump the firmware from flash0: to your memory stick. This will only run on 1.0 Jap PSP's.

Hopefully this will be useful to someone who might be able to rip the firmware from their 1.0 and figure out a way to use that data to downgrade a 1.5 PSP.

I will be sure to let you know once this has happened. It's only a matter of time now
