Hi, would it be possible for you to elaborate upon this solution? Perhaps some file paths would help?
All your plugins are available at C:\Users\Peti\Documents\SimCity 4\Plugins
Just take out any previous plugins add the SimMars stuff in there.
Same with the regions, I believe: C:\Users\Peti\Documents\SimCity 4\Regions
So, just to make sure I have this right,
I copy everything from the SIMMARS_Plugins folder into the Plugins folder, but not the one in the Steam directory, the one in Documents, and the some for regions, correct?
