VPK

The scenes equivalent to sonys PKGS format but in case it's to use with a HENkaku enabled Vitas or PSTVs, it does not use any encryption over the files. So you can not install a VPK with the official PKG Installer and vice verca, VitaShell can not install PKGS files.

Make your own VPK files

Do that the same way just like it will be done for own made PKGS files. But instead of the original encrypted files, use the one from your project or what ever for non-encrypted app files.
