Sony has released a full list of which PSOne Classics titles will be playable on the Vita following this week's system software update.

The system update is reportedly already available in the US, but only Arc the Lad, Cool Boarders 2, Final Fantasy VII, Hot Shots Golf 2, Jet Moto, Syphon Filter, Tomb Raider, Twisted Metal 2 and Wild Arms are available.

However, according to NeoGAF, US users can expand this inventory a bit by downloading the following games to their PlayStation 3 and transferring via media manager: Castlevania: Shadows of the Night, Final Fantasy IX, International Track and Field+, Legacy of Kain: Soul Reaver, Medieval, Metal Gear Solid, Rally Cross, Resident Evil 3: Nemesis, Silent Hill, Wild Arms 2 and Xenogears. The list is constantly expanding as users confirm more titles, so be sure to check back or try your favourite games yourself.

Meanwhile, Vita firmware 1.80 arrives in Europe tomorrow, and will allow you to play a huge slice of the PSOne games available on the PlayStation Store on your snazzy new Vita. Check it out below, courtesy of the EU PS Blog, along with a video demonstrating the feature in action.
