i think i seen somewhere it says if u wanna play games that require 2.0 u just boot up a old game that dosent require and old game and when the white psp screen pops up u eject ur disc and put in your new game that requires 2.0
can someone test this and get back to me i dont have any games that need 1.52 or 2.0
Yeah, it works... But you would probably be better off using the WAB version changer, or possibly a no update loader if you don't want to write to your flash. You should be able to find both files on www.pspupdates.com
