Any level except for Slime Dunk
Check your messages when you get back from the "Stay Puft Marshmallow" level. The new person's father or friend says "You're doing adequate work out there Luke, keep it up!". This reveals that his name is Luke Hoss.
When hunting Slimer, you will find room 1221, the Spider Witch's room. Looking through the Paragoogles at the lower left decoration will reveal a glowing spider.
In the firehouse after the "Shador Island" level, there are Spanish newspapers scattered all over. The headline reads "Un Cubano En El Cosmos", which means "A Cuban in Space".
Go upstairs at Ghostbusters headquarters. You can find a drawing by a child on pink paper hanging near some electrical equipment. The text "To Uncle Egon, from Ed." appears on it. This is a reference to the fan fiction Ghostbusters videos "Freddy vs. Ghostbusters" and "The Return Of The Ghostbusters" which features Egon's nephew Ed Spengler.
When you are in the hotel ballroom with Slimer, press [Action] by the piano to sometimes hear the same notes that Peter played in Dana's apartment in the first movie.
In the "Sedgewick Hotel" level, you will pass room 1204 while hunting for Slimer. Inside you can hear the original Ghostbusters commercial for the movie. This is also a reference to Dana Barrett, who had a habit of leaving her television turned on too loud.
In front of the water fountain in the firehouse is a window looking back into storage. You can see the "Ghostbusters II" sign and some doors from Ecto 1A.
When you are in the firehouse just before returning to the closed-up Sedgewick, play through the phone messages. You will hear a woman asking for the number to Ray's Occult bookstore.
One of the messages on the answering machine is from a Professor Jones who is trying to locate the Vigo painting, stating that it belongs in a museum.
The portrait of Ivo Shandor's mother on Shandor Island is modeled after Francois Boucher's 1750s portrait of Madame de Pompadour, courtesan to Louis the XV of France. Though a political and historically significant figure, she was essentially a prostitute.
Look at one of the monitors on a desk upstairs at the Ghostbusters' headquarters. You can see the ending screen from Ghostbusters on the NES.
One of the messages from the Vigo painting is a reference to the O.J. Simpson trial. It reads, "I see the evil in the times to come. The glove won't fit."
When you are in the firehouse, go down by the containment unit. Look on one of the work desks to see a circular ghost trap that was used in the late 1990's cartoon called The Extreme Ghostbusters.
In the basement, on the far work station there is a PKE meter modeled after the one from The Real Ghostbusters.
When listening to the answering machine messages, one will be of a man talking in a gruff voice asking, "Who busts the Ghostbusters?"
