Here is a cool plugin called XMBattery from PSP developer FrEdDy that when activated elegantly injects itself into the XMB — just like Bubbletune’s Game Categories, which XMBattery is actually based on.

As you can probably tell from the screenshot you’re able to toggle the PSP battery state to/from Normal, Pandora or Autoboot mode. This of course only works on PSP models where Pandora is supported.
