It worked great until a few months ago when it decided not to boot up at all when cutting the game on.
Replaced batteries in small board in head of game in the back, and in Nucore computer. pwr on after power failure is set to ON in the BIOS. Still only boots if you push the button located in the head of the game at the front.
Also, since replacing the battery in the Nucore computer, the video in the game is really slow, like frame by frame slow.
