Homebrew developer Kratosjohn, has released a new theme for the Sony PlayStation Portable called the Sidedock 3.90 M33.

Unlike more conventional themes, this one offers a selection bar on the left side of the XMB. The theme itself looks pretty clean and well made, definitely a plus for those who prefer to take a minimalist approach to their PSP's interface.

That said, be advised that the theme does not include any documentation. If this is the first time you will be installing a theme on your unit, you might want to do a little research to avoid any potential problems.
