Leisure Suit Larry: Magna Cum Laude Cheats

Easy flyer distribution
When they throw an airplane, run towards them with [Left] to grab it beforehand.

Easy money
Go to the Greek Quad and stand near the frat boy who buys pictures. With your back facing the frat boy, take out your camera and snap pictures of the cheerleaders that are practicing. After taking all the pictures, turn around and sell them to the frat boy. He will charge $6 and will give you $4 for each picture. If you stand too close to the cheerleaders they will react to the flash and you will get less money for the pictures. This can be done repeatedly without penalty.

Super camera lens
Interact with the stage light on the left of the Swingles set. When it falls over and breaks, pick up the camera lens icon. Instead of your camera zooming to 5X, it can now zoom to 10x. You can now take closer and better pictures.

Pop culture references
In the sorority house, the names on the doors on the second floor are all grouped by character names from famous television shows or pop culture families:

Janet and LaToya (Jackson Sisters)
Wynonna and Naomi (The Judds).
Thomas, Rick, TC, and Higgins (Magnum PI)
Kelly, Lisa, Jesse, and Screech (Saved by the Bell)
Rose, Dorothy, Sophia, and Blanche (Golden Girls)
Blair, Natalie, Tootie, and Jo (Facts of Life)
Angela, Mona, Samantha, and Jonathan (Who's the Boss?)
Sondra, Denise, Vanessa, Rudy (The Cosby Show)
Sabrina, Jill, Kelly, Stefania, and Andrea (Charlie's Angels)

Goodies
The vibrantly-mohawked Nigel is located in several places throughout the game and he can sell you call kinds of unlockable items (art, strip games, etc). Post-makeover-Russell can do the same for you as well, though, later on in the game.

Porn Fairy
This takes a keen eye but in several places there will be a magazine on the ground with no special actions. Check it in order to get the porn fairy who will say something then leave with a parting gift such as a rare item or multiple secret tokens. The fairy is also found outside of Larry's window after the game is completed and will sell you tapes so you can see the two endings you missed.
