Cheat: Nudity
For the peep hole in the sorority there is a nude girl on the right that is just out of the picture. Change the X and Y axis controls and you will now be able to look far enough over to see the completely naked girl.

Cheat: Watch Movies
In order to switch the opening cinemas of the game with any one of the cut scenes you must rename one of these three files to one of the 18 movies below. Then when you start up the game, the designated cinema will play instead of the intro. Note: Make a backup of the original files before editing them.

Unlockable: Art
If you enter the large gold doors on Nice Street and then go to the right of the doors you will find a man with a mohawk. This man sells the following naughty art:
Naughty 1
Bonus Art 2
Loading Screen 2

Unlockable: Nude mode
First, beat the game. Then buy "Everybody Naked!" at the bar. This secret costs 269 secret tokens and can be turned on in the bonus options of the Extras section.

Hint: 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.

Hint: 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.

Hint: Porn Fairy
Just found this one when you go into the sorority house, go to the upper level where the rooms are. There will be a door with a question mark, activate it and get the porn fairy.
