PSP Backgrounds

[Vampyr]

Like, you know how the original backgrounds move? They function as a screen saver and as a background, because if the same still image is displayed on the PSP for too long a time, it gets burnt that way, and you can see the ghost image of it forever.

But it takes like a few hours of constant viewing for it to get like that.

But just in case I accidently leave it on the desktop, I'm wondering if the automatic stand-by after a couple of minutes eliminate the problem.
