In the Ghostbusters game, if you go to the second floor of the firehouse there is a computer on a desk. If you look closely at the monitor of the computer the ending screen for the original Ghostbuster game for the Nintendo is on there.

Go to the fire house and go to the basement; look in the corner, and you should see a picture of the bad guy in the museum from the second movie.
