I found this link
I love Lost Levels, they rock.
This is a great retro place, because they hunt missing and unreleased games, often pooling money to do so.
The original link was of course posted on http://www.sega-saturn.net/

This game rocks on 3DO, and I am glad it was found.
I have no way to test it yet as I have not yet gotten an Intel Mac, so I cannot use the Saturn emus (Mac has no Saturn emus).
