Using -mod:My_Mod

I wonder if this method works properly.
I prepared a folder named CoH (Conquest of Hispania) with all the files corresponding to my mod and I put it in the root directory of Rome:TotalWar.
I modified the properties of the shortcut of the game by putting -mod:CoH and nothing happened. Even the option "provincial campaign" didn't appear in the main menu.
I created a new empty folder: Data\world\maps\campaign\Hispania and in that case the game detected a provincial campaign and it tried to open it. I got the faction selection menu, but the names and descriptions (in the files of Data\text) did not appear. The modified symbol buttons didn't appear either.
I thought that the game would look for the files in CoH before using those in Data, but it seems that it doesn't happen with all the files, mainly out of the Data\world\maps\campaign\Hispania folder.
Does anybody have more experience with this method?
Thanks.

You need to put all the world files that tell you 'about the map' in the Data\world\maps\campaign\Hispania (in your case) folder. The only world files that the -mod:my_mod switch makes the game look for in your my_mod folder (CoH\world\maps\campaign\Hispania in your case) are those that are 'about the campaign'. Specifically:
descr_strat.txt
leader_pic_{faction}.tga
map_{faction}.tga

This should get your campaign working. Unfortunately, it seems that the -mod:my_mod switch is still not fully functional: you cannot play custom battles when using this switch.

If I copy all the files from my 'my_mod' folder into the data folder, and run the game without the switch, I can play custom battles no problem. But with the switch, it just stays at whatever screen it's at when you click the 'start battle' button, and gives no error on exit. The campaign works with the switch, as do battles within the campaign, but not custom battles. I've tried copying pretty much the entire contents (i.e. every sub-folder) of the data folder into the my_mod folder, but to no avail. Hence my arriving at the above conclusion: that custom battles do not work with the switch.

Has anyone managed to in fact get them to work using this switch?

Can someone give me an utter moron's guide to setting up the files correctly for the -mod:XXX command to work, please? I've got my work in progress frogmod on a seperate, complete copy of my RTW install; it seems a bit daft to ignore a handy, space saving feature.

The frogmod currently consists of just two altered .txt files: export_descr_buildings and export_descr_units. Everything else is as in the vanilla 1.2.

I have set up the new shortcut with the -mod:frogmod command successfully. The rest ... er, assume disaster. :yes:

Hopefully this will help:
