Unlocking all parks in RCT 1 and 2
Is there anyway to unlock all the parks by a cheat in the game? So you don't have to try and pass all of the park scenarios.
For RollerCoaster Tycoon 1, I don't know if there's one.
For RollerCoaster Tycoon 2, you don't have to unlock any park (unless I don't know about parks to unlock)
