Surprisingly little in some cases. I worked on them for a number of years. One simulator I had experience with could be changed from a Level C to D with flight panel change and by re-booting the host computers with a different software package. It changed the physical device from one variant to another on the same basic airframe i.e., a 737-200 to a 737-300 as an example. Took about 15 minutes. Each had a separate certification from the FAA even though it was the same simulator.
