I have a few questions concerning PSP ISOs. I'm considering getting a PSP for my birthday, however, I'd like to know a few things first.
First, how do you run PSP ISOs on PSP?
Second, is online mode effected if I use an ISO rather than the real game?
Third, what firmware do I need to run ISOs?
Forth, what games force you to upgrade the firmware?
Finally, is there a way to downgrade the firmware if nessicery?
