Rescue Rover 2

Buried within the file are the lyrics to the Dognapped theme song (which make you glad that digital voice wasn't common in 1993):

Now the time has come

You've got to rescue Rusty, boom boom

The Robots took him to their Robot Rooms

and they are all a'guarding him with guns and lasers

and you gotta get him back

Because he is your dog.

Also, if you look at the screenshots, you'll notice that the boy trying to rescue Rusty is African-American. One of the first (and few) to have a leading role in a computer game.
