PSP Hack 6.60

to make this work, you need to plug your psp into your computer then click on it and go to the folder named psp then game and put the files there. then unplug your psp and go to the game spot on it where downloaded games and umds would show up and click pro update, it will pop up with something you might think is bad just keep pressing x after its done plug your psp back into your computer and delete the files, then go back to where you can see the folder named psp and make a new folder named ISO it needs to be in all caps, after you do that put your iso files in there, it worked for me and im sure it will work for you, if it doesn't then comment and i'll do my best to help you get it working
