Most likely it's for the Intellivision as Dreadnaught Factor was not released for the C64. The Beamrider cart is probably for the Intellivision as well.

You're not the first one to find these however...
Given its a 3D0 game technically, it would probably work best on a 3D0 emulator and not a laserdisc emulator. MAME supposedly has arcade drivers for it.
I need to come back over there - there are two prototype versions of the game code. The second proto the starting level is different and the bonus stages allow you to do them over and over. GGA has swapped discs and is running the other version now, which the difficulty is harder.

Ugh. He's been very unhappy with how Youtube has treated creators of late and is wanting to move out.
National Videogame Museum in Frisco, TX is wondering about a white case 2600 that was found and is being displayed. Since the 2600 jr. was in a black case, this has to be a proto. They are looking for info on it.
