I assembled a 7-zip file containing a copy of version 0.82 of SH3Gen and a zipfile containing GlobalExplorer's webcontent, and asked Sailor Steve to upload it to the download section:

So no more worries about availability anymore.
(also contains a textfile with a current link to the free Tatukgis viewer. Needs registration though.)
