game is far from complete- not even sure if you can actually lose, for example, but core game mechanics and playability exist and features as listed on the joystiq mention.
While "copy 2", probably the only build that was ever distributed.
Game functions correctly, has an odd SFO, but works fine both on dev/test tool and hacked psp (if converted to a proper iso)

 

no ideas on what it's worth people?
I've also converted it to a psp playable iso and would provide that to an end buyer if that would help the value.
