All, I have been trying to run the Killzone ISO, and it starts up OK, but then when it actualy goes to load the level, it shuts the PSP down. I am able to play Ratchet and Star Wars Renegade Squadron. My PSP is running 3.52 M33-4. I had recently upgraded from 3.40 OE-A to 3.52 M33-4. I tried searching but couldn't find anyhing solid to go on. Hopefully it's a seting in the configuration, but I haven't locked it down yet. Thanks in advance for any help!
