installing rePatch plugin seems to fix.

maybe we should add this special requirement for vita users ?

This is a bug in Henkaku but who's in charge of it (Molecule Team) doesn't care of fixing it. (Proposed a fix with connected PR like an year ago and still this is unsolved). Most likely will never be addressed so rePatch will be required.
