No M9000 games used a video topper. They were all single screen games with a plexi for the top box. Then the V20/20's came out with dual wide screens, but no video topper. If you have a single screen M9000 (with the 4:3 aspect ratio), you could try connecting the secondary video to the topper to see if you get the graphics on games meant for the V20/20, the video topper would then display the contents meant for the 2nd screen. You can also install a video topper and connect it to a media player to play theme related videos above. User Coolwave has made a bunch of different ones which he has graciously shared within this community.
