Extract/transfer scenarios

[Scipio]

I have made a few attempts in the past to swap scenarios between the different CMx2 versions, with varying degrees of success. Sometimes it is enough to adjust a special hex number to the respective CMx2 version with a hex editor to at least load the map into the editor of another CMx2.
However, this still often goes wrong and you always have to redo the complete OOB. So I thought about transferring the somehow packed and/or encrypted scenario data into a raw form or extracting, analyzing and cleanly transferring the contained data, even if the OOB is not that easy to do.
Mad Mike, for example, had some success reading out the scenario parameters. Has anyone ever achieved more than that, or could one achieve more with the same technique?
