I have an original CD ROM of the game. When trying to start a game on CorsixTH, it warns me this when I get to the menu screen when I press Campaign (single scenario starts fine):
There appears to be corrupt files in your Theme Hospital folder, so don't be surprised if CorsixTH crashes. At least the following files are wrong:
INTRO\INTRO.sm4 (This file is missing)
Please make sure you point the game to a valid copy of the data files from the original game, as said files are required for graphics and sounds.
Then if I continue, it freezes on the first animation screen with the board game. I have tried uninstalling the original TH and reinstalling it, and as far as I know I am pointing it to the correct file so I am not sure what I am doing wrong. Any assistance gratefully received!
