VPK

The scene's equivalent to Sony's PKGS format but in this case it's to be used with a HENkaku enabled PS Vitas or PSTV. 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 that the same way just like it will be done for self-made PKGS files but instead of the original encrypted files, use the onse from your project or from another place for non-encrypted app files.
