Thank you very much for your answer.
I still did not get the old version to run using a virtual image. Maybe this has to do with it not being the original CD version, but some version from a game magazine.
I guess I have to use the second approach. Unfortunately, I was already further advanced in the game than the blessing ceremony, it was really very close to the end. I guess I have to repeat this part of the game after all. Good thing I keep my old savegames (almost 5GB), so there should be one from just before the blessing ceremony.
