hey guys, I found a workaround for the load and crash issue on Roller Coaster Tycoon.

install and run the game, once you save your game, quit and then go to the roller coaster tycoon save directory, once your there
shift + right click, then open with, hit other application, look for rct.exe double click on it and done.

Whenever you want to run a save game simply double click the file.
