A playable demo for the upcoming PSP game Dragon Ball TAG VS is available on the Japanese PlayStation store:

The demo is fully playable on any region PSP, though you will need to be running system software 6.30 or later. The demo is also available directly from Namco-Bandai’s website (mirror 1 / mirror 2); you will need to extract the game files (~130 MB) to your memory stick to transfer over to the PSP system if you go this route, rather than downloading directly to the memory stick on the PSP itself (or PS3) via the PlayStation Store. We will have some initial thoughts for you on this weekend’s upcoming podcast episode!

TAG VS is due out for the PSP in Japan 30 September 2010 for ¥5229, while the game will see its release (as Tenkaichi Tag Team) in North America on 19 October 2010 for $39.99.
