The name’s the deal – this changes your wallpaper for the XMB, no more, no less.

Release notes:

And here we are:
HELLCATs Wallpaper Changer

The name’s the deal – this changes your wallpaper for the XMB, no more, no less

However you have a few features:
Two modes of operation: “Everytime” and “Once per day” (see readme for details)
You can set special, predefined images for a specific date (again, check readme)
(the last one lets you set a fixed wallpaper for the specified date instead of using an all random one)

That’s it.
Short and painless.
Maybe someone might like it
