All controls and sound function perfectly with fast response. It runs on 4 'C' batteries or power adaptor (not supplied but available in my other listings) - please see video to see and hear it working (any flashing on the display is due to camera shutter speed - not the game itself).
The battery contacts are very clean with no previous leaks, and the original battery cover is present.
Please see the photos for the true item condition, as these are of the exact item for sale, taken at the time of listing. This one is in fantastic overall condition, with no cracks and a good springy joystick/buttons. There are only very minor signs of use over it's 41 year life - one of the very cleanest game examples I've seen (even the base is in amazing reflective condition).
The box is also included. It is still sturdy and bright. It has minor shelf wear, but still does the job and looks great (see photos)! The original instructions, warranty card, colour product booklet and even the rare yellow 'sound information' card are also present.
