Ok so I downgraded to 1.5, and I have some homebrew on my psp. I wanna play GTA though. So I download the WAB version changer. When I opened it on my psp I pressed triangle for the patched 2.0. So it said I had 2.0 now, then when I went to play GTA it said the game could not be started, and the error was FFFFFFED3. Could someone help me out? Or link me to a tutorial on how to use the downgrader??? Sorry if this is a dumb question or wrong forum. Thanks.
