"Roller-coaster Tycoon" allows you to build your own theme park complete with attractions, concession stands and roller coasters. Through normal game play and completing the scenarios, you are unable to unlock different kinds of roller coasters; however, some players may wish to have access to them immediately. You are unable to unlock all coasters along with the money to build them immediately by entering a cheat code at the main menu.
Start "Rollercoaster Tycoon" by double-clicking its launch icon on your desktop or launching it from the "Start" menu.
Hold the "Shift" button down when you arrive at the main menu of the game. While holding "Shift" type in "rct2" without the quotation marks on your keyboard. Clapping will be heard when the cheat code has been entered properly.
Choose a scenario to play from the main menu. You should now have all items unlocked as well as an infinite supply of money.
The cheat code will need to be reapplied every time you launch Rollercoaster Tycoon.
