Hello everyone! I recently updated via system update my PSP-2000 to a 6.38 system, hoping to add more games to run in my ISO folder. The update was successful,however, I could no longer play games from the ISO folder and could no long further update or downgrade. I'm a newbie in modifying PSP systems, and would very much appreciate all the help I could get in updating it to the most ideal firmware (that allows it to play more games (or game types) in the iso folder). Thanks in advance.
