A few days ago we reported on the PS3 SFO editor by
Red_Squirrel, today he has released a new application known as
PS3 Package GUI Linux Edition.
To quote:
What's it? It's a simple Linux GUI for the Sony's SDK make_package_npdrm tool. With this tool you can extract free PS3's packages (.PKG files) or make your own homebrew packages to install them in your Jailbroken PS3.
You can ask Red_Squirrel any questions, comments, or bug reporting at the release thread
here.
You can download the PS3 Package GUI LE below
