It appears that Sony have released yet another update to the PS Vita, this time in the form of firmware update 1.67.
The firmware is currently optional however as all online activity can still be accessed.
*Update* American websites claim this update is mandatory for them, however for this EU user it was not.
RabidWalker from the PlayStation forums has confirmed that the update is an optional update that improves stability on some PS Vita titles, some of which include Dream Club Zero Portable, which thesixthaxis.com mentioned earlier today.
How do you feel about these constant mini updates to the PS Vita? Personally I’m happy, they take only a few moments to download and you know Sony are constantly tweaking the machine to provide us with the best experience. Let us know your thoughts in the comments section below.
