The first firmware update for Sony’s PlayStation Vita has been released today, fixing an issue that affected progress in Shin Sangoku Musou (game). Unlike the expected, this update does not solve any of the issues which have been reported by vrious users, but also to note that Sony hasn’t acknowledged those issues yet. One can update to the latest firmware battery around half full on the Play Station Vita. However, PSP users had to have a full charge to perform firmware update.
