Help with the FileAssistant

has anyone here used the FileAssistant?? Cuz I need help with the Skin thingy, I want to know how to change the skin and so on, but it won't let me...what am I suppose to do?

do u mean the of the actual psp in real life?Its impossible unless u made it.But what do u mean/

When it says skin, and then like default, is there a way where I can put other theme into there? another file I'm suppose to know about? Help?

Well I dont think there is a way to get ur own theme but u can have ur own wallpaper/(I serously dont no wat the difference is)
to get ur own wall paper is I go into my photo section, look at the photo I want, preview it by pressing the X button and then I press Triangle and click on View As Wallpaper or something like that.
