Well if that a JAMMA cabinet, which I'm almost certain it will be, you can put pretty much any modern game in it by buying the PCB's for it.
JAMMA is an arcade standard if you aren't familiar with it, although others on this board can explain it much better than I. Basically, you'd just need to replace the SF boards with new ones.
As for info, you're on a great site full of it. Go read the rest of the site, and the other posts on this forum. You'll learn a LOT
EDIT:
http://www.klov.com/game_detail.php?letter=&game_id=9829 There's some info about your game on that link. It is a JAMMA game, so you're set to put in any other game that is JAMMA.
