PSPiton is a simple application which will help you downgrading/upgrading your PSP to the firmware you need for your games. It also contains alot of real usefull information of other good apps/homebrew, such as CWCheat, Ultimate PSPTube and their links.

Changes:

– More apps added;
– Splitted the application into 2 differend versions: full and lite (full doesn’t require to download every single app, because they are already included. The lite version does require to download them, but
the lite version is alot smaller;
– Fixed a bug which caused to close PSPiton if you pressed home or end;
– Fixed a bug which showed incorrect information of some apps/homebrew;
– Readme added;
– Pressing the PSPiton logo doesn’t cause showing up the credits anymore;
– Updated PSPfiler;
– Updated Pandora Deluxe;
– Added a second page, so I can add more apps in nearby future;
– Added the ability to resize the windowed mode to fullscreen mode (Maybe will be removed in the upcoming version).
