This only started to happen a few hours ago. I have been using the same gameboot for a few weeks already, and up until this point I've never had this problem. Whenever I try to start up my UMD, the gameboot plays, but freezes after it finishes and then automatically shuts the PSP off. Popstation and homebrew work fine, though. I know this isn't a hardware malfunction because it can read the UMD (I've had that problem before).
Can anyone help me out on this one?
