Jurassic Park: Operation Genesis Cheats

Ok I've had this game sence October 30, 2009 and last year I found out something really really cool and nobody on youtube has done it!
Ok I decided to take the disk out and put it in again because it was really slow, but when I put it back in a menu poped up.It had all sorts of options on it.I put it all on high (ecsept the treane detail which I put to medium because thats as high as it will go). And when I turned it on I had all the buildings I had in the first place but they looked alot cooler like one example was the visitor centor. It looked exatly like the one in the movie "Jurassic Park"! They didn't do anything different but it was so cool.
Now I'll tell you how to do it.
#1. Insert your disk and wate for a new menu to appear.
#2. Put all the settings on high.
#3.Then play with your new buildings.
PS: it also changes the fences too so everything you build will look much cooler. So thats it. Contact me if you have any questions :)
