All I can say is wow.. My friend's PSP is having problems so I took a look at its flash0/1 drives.. I accessed flash1.. or the 0.. whatever.. its the one with the registries..
Wow.. A 2 gig file.. with 2 weird folders.. there should only be that registry folder and the config.se file..
I can't delete, open, and rename those 2 weird folders and 2 gig file.. I'm trying everything but it says it's in use..
