I'm wondering if this game has the old cheat for unlimited money from when I used to play it on the 3DO (or was it the CDI? I can't remember)... I think it's the BOVINE cheat... or any other cheats that I can use in the game? I'm just a builder, not a businessman :)

I'm playing on a Mac, if that matters.

I don't know let me just copy paste it from the cheatbook database:

Build a gambling game (e.g. duck shoot etc) and put: the price per game up to max
the price of the prize to the minimum and the chance of wining to 75. You should
rake in the cash. The more you biuld the more you earn.

Drive on water:
---------------
If you put the entranceway of the race car ride by a complete rubber tubing track,
your customers can literally drive on water. The same thing happens for the race
car ride, only you use the rubber tubing entranceway.


Unable to change your age:
--------------------------
In the information menu, click where it reads "Age". Hold 1, then click on something
else. If done correctly, your age will change to 127 and you will not be able to
change your name.


Cheap roller coaster:
---------------------
Place a roller coaster entrance at any location, then build the smallest loop possible
with the least amount of sections. Open the ride, then immediately close it. The game
will charge your account for the small ride. Remove the small loop and build any
sections as desired to the ride without being charged.
