How to figure out a psp password
well if you just acidentilly put the password on and didn't change it to what you wanted then the password should be something simple like "9999" or something. If you're trying to get into someone elses I don't know if there's any way to hack in.
you shold just have to go into your sytm settings and reset everything to factry defaults it will reset any paswrod you had.
if its a hacked psp go into safe mode
