I forgot all about this game. I used to play it way-back-when. I think to kill time when Moon Patrol, Robotron and Xevious were already being played.
Edit: I tried this in MAME and it works, but I'm having difficulty remembering the controls. In MAME, the stick both whips and moves the guy, and the trackball just moves him. Is the stick supposed to just whip without moving the character, or the trackball? Couldn't make it out from the CP images in the auction.
