as for the original person's question, u can use the updater within the psp, or download the update file(make sure its JP, US or whatever your psp is, tho im not quite sure it will make a diff, but best be safe), save it in your game folder, and run it from there to update. so once 2.0 is hacked(not for a while i dont think tho) u can just download the 2.0 update file to update
