Hello

Is there an easy way to change the active ruleset in a savegame file? Changing from standard to "rise and fall".
I have the first savegame file from 4000BC, and I don't want to start another game where the resources and player placements are different.

How can I make a mod from a savegame?

Thanks

So far as I know it is impossible unless you can "crack" the saved game file format and directly edit the data therein.

However, this would still not work since a change in Ruleset from say RaF to GS alters the game's database and Row ID #s within the database's game-tables in too many different ways. So the saved game would expect UNIT_SOMETHING to have an ID # of 27 from within the Units table (for example) but that unit might not even exist in the new Ruleset or might have a different ID #. New concepts like floodable tiles would need to be implemented in such an example Ruleset Change, but the map for the original save of the game would not have any floodable tiles since it is not a RaF concept.

Thanks LeeS for clarifying
Actually I only want to change the ruleset from standard to RaF. So no issue with floodable tiles. Unless there is something else in RaF.
I did change the difficulty in the savegame with a hex editor. But changing thr ruleset seems to be not that easy.

The only other way I can think of is to make a mod with the map and starting positions (resources, players) from the savegame. But I would have to check the available tools and learn how to apply them. Any tips how to do this?
