Sony's just-released v1.80 PlayStation Vita firmware update has finally added support for PSone games.

A huge list of titles are supported (see below) and will be made available to download from the EU PlayStation Store tomorrow, Sony has said.

Those who have already bought and installed the games on PlayStation 3 can transfer them over.

In North America, only a fraction of the games are listed for re-release this week by the US PlayStation blog - although Reddit has compiled a list of titles which can still be played via PS3 transfer.

What else do you get in v1.80? Well, the Vita's new Cross-Controller feature allows you to use it as a PlayStation 3 controller within compatible PS3 titles, such as LittleBigPlanet 2. The handheld's home screen and Videos/Music apps now offer button support, Music now supports playlists (you can export them from iTunes) and the web browser now includes handy rear-touch scrolling.

There's some extra video controls, improvements for Maps and the ability to retroactively add location data to near by using close-by Wi-Fi access points (even if you're not connected).
