I am having problems with a couple of PSP games (Parappa the Rapper, Traxxpad, and Ratatouille). I get the error message, "This game cannot be started (80020148). For some wierd reason, my system version is blank, but I know the last time I updated it, it showed 3.03 OE. I went on UMDGen and it seems like the software versions needed to use are 3.11 and above. I want to update my firmware to 3.40 OE, but before I do I want to be sure this is the right move. I also made sure my umd was not enabled in the recovery section. Is my next step upgrading to 3.40 OE or should I do something different? I don't want to brick my PSP!
