I might still have the contrib somewhere, but a better place to look
is http://www.m17n.org/dodes/ecos/. That takes you to a CVS repository
containing
http://cvs.m17n.org/cgi-bin/viewcvs/ecos/ecos/packages/fs/iso/?cvsroot=superh
You should also be aware that a dreamcast does not have an ordinary CD
drive. Instead it has a GD drive with ~1GB capacity. From another
website:
"A GD-ROM disk actually consits of two data regions, separated by a
data-less separator ring. The inner region contains a normal Yellow
Book CD-ROM track, and a Red Book CD-DA track. This region can be read
in any CD drive. The outer region (outside the separator ring) is the
high-density area which contains the actual game data (both files and
CD-DA audio)."
I don't know if that affected the ISO support, they may have supported
the inner region only.
