There is no guarantee that these cheats will work for you. I have tested them all,but there seems to be an issue with computers running on Windows XP.
This requires you to do some file editing, but it's very easy. Open the zoo.ini in your Zoo Tycoon directory with notepad or a similar text editor. Find the line that says "MSMaxCash". Change the figure next to it to whatever you want. This will change the maximum amount of money you can choose from when you start a zoo in the sandbox mode, for example.
Sick of paying high wages? :
Find the zoo.ini file as in the above cheat. Find the config.ztd file and open it with winzip. Open the economy.cfg file to edit and scroll down until you find
and set the values at whatever you want. This is a great way to keep your zoo making a profit, as staff is a HUGE expense every month.
Additional Money (2):
Press Shift 4 (basically like typing the $), and you'll get an instant $10,000. Please use caution with this one, as it will make your fences deteriorate every time you use it!
Unlock the Triceratops:
Name one of your exhibits "Cretaceous Corral". This will unlock the Triceratops. I should also note that if you name a brand new exhibit using this cheat, it will crash the game. Everyone who's done it with a new exhibit has experienced this, so keep it in mind.
Unlock the Unicorn:
Name one of your exhibits "Xanadu". This will unlock the Unicorn. I should also note that if you name a brand new exhibit using this cheat, it will crash the game. Everyone who's done it with a new exhibit has experienced this, so keep it in mind.
Yellow Brick Path:
Place a lion, tiger, and a bear in the same exhibit.
CHANGE PEOPLE'S NAMES TO:
Mr. Blue - Changes everyone's shirt blue.
Mr. Blonde - Changes everyone's shirt to yellow.
Mr. White - Changes everyone's shirt to white.
Mr. Brown - Changes everyone's shirt to brown.
Mr. Orange - Changes everyone's shirt to orange.
Mr. Pink - Change's everyone's shirt to pink.
