Does anyone know if there is a cheat or trainer to get large peeps in your park?

I've never heard of a cheat for that.

There is a genius over at the Atari forums by the name of DarkSim. Somehow he made it to where the peeps didn't have a head. Plainly they went around headless. If that's possible then I'm sure large peeps are also. Ask around.

I think there might be a cheat for the headless thing but not sure, you could hack into the game to get huge peeps but it is risky.
