The PS3 SELF loader will load the files directly without the need to package them. Just FTP them over to your PS3 or place them on a USB stick and load them.
From the NFO File: b0xloader - SELF Loader 1.0
A Simple SELF launcher for the Playstation 3.
Install the package to PS3
Select a Fake signed SELF from the menu and press X to launch.
The SELF you are launching must be "fake signed" for it to launch, if not it will bring you back to XMB, This is good for quick testing your development/test builds without repacking to a PKG every time. Future support will be added for non-signed SELF/ELF's
