When you download rides where do you put the file ?
Go to to My Documents, click on the RCT3 Folder. It will open up and there will be a lot of diferrent folders named pools, coasters, etc. Just move the file to the correct folder and it is ready to be loaded in the game!
Yah, the rides should be able to be put in your park as soon as they're in the "coasters" folder in the "RCT3" folder in "My Documents" on Windows XP.
