1) Galaga with stars background removed (just change &h018D address byte from &H20 to 0). This game works natively with color 0 
;
2) A panasonic FS-UV1 video telopper ;
3) A DVD player running Nasa's Earth time lapse from ISS ;
and voilá !-> http://www.youtube.com/watch?v=yMd6tKhAKGQ
Hahaha, cool!. Looks like a LD Galaga version 
"That man is playing Galaga !" 
Very nice
With a little knowledge, you must do this with R-Type:
1) We need to create the template => http://youtu.be/S20G-pwZdLE
2) Modify the program cartridge to enable SET VIDEO 2,0,0 in game.
In theory you should get something like this: => http://youtu.be/Jzo5gMVjXyw
To put decorations as background with galaga, we must "be" as black or transparent. with this solution, it is not necessary to synchronize the sets which is much easier.
There are a few months, I tried without modification Manbow 2 and this is what we get:

Very cool carlosemandrade! 
Thats awesome with Galaga!!
This is exactly what I want to do but with my video background
would be best to get to do the same thing with a HBG900 by managing the DVD with RS232 interface , it would be fun
And it is feasible because these remote controlled drives exist
