Ok I figured it out.
I extracted your WSEmod.big file, took all the map mp folders and put them in my maps folder, now I can skirmish on all of your maps.
Just out of curiosity what is the rest of the stuff in the mod file for, i.e. the data and art folders. Am I missing out on something here by only using the map files?
Thanks
Glad to hear it works. Just remember, if any of the unofficial patch's features were created by map file edits, those features will be missing from gameplay.
The art folder has only a new logo with the mod title text. The map.ini file associated with each map file has the setting to disable the hardware fog (which gets quite murky with a higher camera elevation). I *think* the data folder has only one or two changes to the gamedata.ini file--all the other ini and inc files are just redundant. They are included simply because I got the mod working in that state and released just before a deadline, and I never went back and culled them to trim the unneeded files. In short, I don't think you're missing anything major with your current solution. With the Triplehead mods it would be more complicated.
