Actually, if you have a remote controllable DVD/blueray/video player, you could make a system very similar to the Palcom LD system, just with modern media. The game simply selects the video to be played. Then you can actually make sure the images behind your game are matching the game progress/status.
"I use the video output signal from PLAYSONIQ (SMS VDP) and I think it may be controlled through BASIC/Machine Code for nice visual effects like 2nd background with all the features of Sega Master Smooth scrolling, 64 extra Sprites and 256 Extra Tiles + 32 Extra Colors"
