Was able to create the map and update a new ANTIETAM scenario.
Here is the link to the Antietam Scenario files....

The map files should go into the MAP folder and the Antietam_Standard_S files should go into the SCENARIO folder.
Enjoy!
If there is enough interest I might create the SHILOH and GETTYSBURG scenarios too.
