Cheats for Roller Coaster Tycoon won't work!

I found cheats for the game Roller Coaster Tycoon at CNet GameCenter. Yet the only ones that seem to work are changing the guests name to get a certain action from them. The rest of the cheats like "unlimmited money" won't work.

I'm running version 1.08.172. Has anyone had the cheats work for them? How did you do them? Thanks
