Homebrew developer Hellcat dropped by QJ.NET PSP Development Forum and released an updated version of the application Wallpaper Changer / Randomizer for the Sony PlayStation Portable.

Just like the name of the program implies, this gives users the ability to easily change the wallpapers in their Sony handheld's XMB. The release bumps the program up to version 1.10 and here are the changes specific to this build:

* Added capability of changing/randomizing the background *BEHIND* the XMB wave lines (WITHOUT touching the flash0:! So, perfectly save ) Read the notes about this in the readme when having trouble with it!
* Wallpapers are now finally copied BEFORE the XMB loads, so you see the change imediately, not at the next reboot
* Major internal changes (making the plugin pure kernel mode and dealing with the consequences), the usual bug hunting and some cleaning up of the code.

Just like the coder Hellcat said, it would be good if you browse the documentation first to avoid any problems. It should provide you with added notes, and instructions during installation and usage.
