How to merge Magna Carta and RTW?

[Epistolary Richard]

No, you need to at least also replace the descr_model_battle file, the export_units file, the export_descr_buildings file and the export_buildings file (or edit edb to build the right units), and possibly more.

Perhaps it would be easier to insert the maps of Magna Carta as a provincial campaign in the RTR mod.
At first sight you should copy the whole folder of Magna Carta and edit there descr_strat and descr_mercenaries with the units of RTR.
You must also include the Magna_Carta_regions_and_settlements_bla_bla in the text folder.
The major problem will be the rebels. It would be necessary to include the new rebels in the corresponding files (descr_rebel_factions, or something like that), checking that all the rebel factions in Magna Carta are collected there.

Perhaps I didn't explain it very clearly, but I have not the game here. Sorry!

OK, I started working on it. Thanks for the tips
