This should help people that want to add their own touch to a theme that’s already made.
This program unpacks Playstation 3 Theme files (.p3t). By default, it will extract the contents of the theme file to the directory ‘extracted’ in the current directory.
This program is still in alpha stage and probably has some bugs, if you find any you can contact the creator on the link below.
Please note that PS3-Themes.com is not the creator of this extractor, we don’t provide any support on how to use it other than the community help you can get from our forums.
