The team behind the original HENkaku has also released taiHEN. taiHEN is a framework on which the newest version of HENkaku runs. It is a way to load plugins at the system level like you were used to on the PSP allowing you to change/add function to your console.[1] Enso is a bootloader vulnerability of the Vita that make HENkaku permanent and allows to run itself on the boot. So the Vita has a full CFW with HENkaku taiHEN and Enso.
