VPK

The scene's equivalent to Sony's PKGS format but in this case it's to be used with a HENkaku-enabled PS Vita or PS TV. It does not use any encryption over files so you can not install a VPK with the official PKG installer and vice versa. VitaShell can not install PKGS files.

Make your own VPK files

Do it the same it would be done for self-made PKGS files but instead of the original encrypted files, use the ones from your project or from another place for non-encrypted app files.
