galaxy forge maps will work in sins in the program files galaxy folder, BUT in entrenchment 1.000 & 1.01 you HAVE TO EDIT the entrenchement galaxy.manifest to include the maps in the galaxy folder,
BUT
for entrenchment 1.02 and later and also sins 1.16+ the BEST location to placve the maps is in the GALAXYFORGE folder next to your mods folders
the galaxy forge maps NEED to be placed here for xp
C:\Documents and Settings\'user name'\Local Settings\Application Data\Ironclad Games\Sins of a Solar Empire\GalaxyForge
or here for vista/windows 7
C:\Users\'user name'\AppData\Local\Ironclad Games\Sins of a Solar Empire\GalaxyForge.
NOTE the first two folders after the 'user name' are hidden , so to see them you must first click on 'tools' then 'folder options', then 'view', then click on 'show hidden files& folders' then click ok, then you will be able to browse your want to the folder. I suggest when you find the folder that you create a shortcut to it on the desktop
also the galaxy forge maps only show up in the galaxy forge tab of map types
hope this helps
