Victory conditions

I started the game and is going well but I want to change the victory conditions. How can I change victory conditions without starting a new game?

Gramphos' Civ3 CopyTool can change them for regular civ 3 games, I don't think he's updated it to handle PtW saves though.

If it is a PtW save, post it (and which victory conditions you want to change), and I'll manually do it. Was going to look into the format anyways.
