Open campaign in the editor.

.h3c "Chronicles" unpacked from .lod cannot be opened by either the SoD or WoG editor:

---------------------------
Campaign Editor for Heroes of Might and Magic® III
---------------------------
Incorrect campaign file version!

File version: 7
Current version: 6
---------------------------
OK
---------------------------

Patching the file manually so that it opens is quite difficult (those interested can check the format at http://heroescommunity.com/viewthread.php3?TID=25570&PID=593180), so to view the maps, use the link from #2, where this has already been done.
