Hi everyone. Ok i got a pre-used psp 3000 yesterday running firmware 6.60 soo following instructions i installed temporary pro cfw 6.60. Ok it works perfectly but i was wondering if this cfw can run plugins like cwcheat. If so how??? And if not is it possible to determine the age of my psp to see what firmware it originally had at purchase? This would help me figure out if i can downgrade firmware somehow. Oh and one last question is there a plugin to backup your umds and is that plugin avaliable for pro 6.60 cfw. Sorry if this has been asked before but i cant find the answers anywhere. Plz help. much appreciated. Thanks!!!
