i got one of these things years ago, and the actual website seems to have pretty much abandoned all support for it. but they are still hosting the files, even though the links don't seem to be public, so i thought i'd put all the links i'd found here, it might be helpful to someone else some day.
im linking to these files for archival and reference purposes, i don't own any of these files, i claim no copyright, use at your own risk.
