Looks like CULTURE_CITY_ART needs to be set to 1 in GlobalDefineALT. The code needs some cleaning up though. It adds m_eArtStyleType and doesn't use it at all. I haven't checked all the code, but from what I can tell, it can be made into a minimalistic modcomp where it mods just one function in the DLL and doesn't need XML stuff. Cool modcomp btw.
