None, just a pure EB 1.2 with fixes applied.
In the Romani campaign, though, I have eased the trigger for Marians (this should not have any effect on the game now so vanilla EB 1.2 should be working nice) and enabled the syracusan and massilian hoplites (if you disband those I currently have, it should work fine with vanilla EB 1.2 as well).
The Baktria campaign should be clean completely.
