If you've been aching to wile away hundreds more hours replaying Final Fantasy classics on the go, then Sony Japan's got some good news for you. It's finally revealed that the ability to play those charming, if a little dated, PSOne titles will arrive on the PS Vita's next software update, version 1.80, later this summer. This little nugget was tucked away behind the news that a handful of PS2 titles, playable on all versions of the PS3, will launch in the Japanese PlayStation Store on July 25th. The first wave of titles include Biohazard Code: Veronica, Siren and Dragon Force, all priced between 800 and 1,200 yen. No news yet, however, on when (or if) a similar retro-gaming bounty will arrive outside of Japan.
