So I downloaded it from the newest link and put it in the Civ III Complete/Conquests/Scenarios folder
With only a very few exceptions, this is (usually) the correct place to put user-made CivIIIConquests mods.
In both case, the Mystara mod doesn't show up in the list. Any suggestion why?
When you click on the 'Civ-Content' option, the game compiles a list of all the .biq (ruleset) files which it can see inside the
.../Civ III Complete/Conquests/Scenarios/ folder* — but it will not look inside any subfolders within that folder.
So if you're not seeing the D&D Mystara .biq files, then it follows that it/they cannot currently be in the correct location.
So first of all, are you sure that you downloaded all the files?
The Mystara.rar file in
@Civinator's linked page at CivForum.de
Here, is the mainfile for this mod, and contains everything you need to run it: 4 .biq files, and the 'D&D Mystara' folder containing the art, sound, and text files. Having downloaded that file, the simplest procedure would then be to extract all that content to your desktop, and then copy and move it across to
.../Civ III Complete/Conquests/Scenarios/
The individual .rar files in Civinator's 2nd post in the CivForum thread are the individually zipped .biq files, and
probably not needed, as they appear to be the same .biqs as supplied with the mainfile. That said, his D&D-Mystara-World Map.rar will likely work
better than the one in the mainfile, so you might want to DL it and overwrite the 'original' one.
If you didn't follow the above procedure, you may be suffering from the 'folder-within-a-folder' problem. If you extracted the
Mystara.rar directly to
.../Civ III Complete/Conquests/Scenarios/, it is possible that you ended up with a 'duplicated' subdirectory-structure, like this:
.../Civ III Complete/Conquests/Scenarios/Mystara/D&D Mystara/.
If that's what's happened, then all 4 .biqs in the
.../Scenarios/Mystara/ folder need to be moved up one level, to ...
/Scenarios/. Then the folders in the lower-level
.../Scenarios/Mystara/D&D Mystara/ subfolder should be moved up to the
.../Scenarios/Mystara/ folder, which should in turn be renamed to ...
/Scenarios/D&D Mystara/
(The now-empty
.../D&D Mystara/D&D Mystara/ subfolder can be deleted for tidiness, or left in place, doesn't matter)
