It is possible so long as all elements of the map that concern saving and loading are indentical in both maps. What that is, that's difficult to say, depends on what your savecode saves and how it saves it, but generaly speaking, to be on the safe side, before copying the map and making multiple of them, you would have to finish all the object editor work on anything save code related, so, all heroes and items and anything else you can transferr between maps with the save code would have to be made first for all maps. And the savecode itself, of course. |
