I guess the SGL OS 3.02 was not distributed to very many developers due to it being released so late in the Saturns lifetime. I guess it was used to do the unreleased ports of Virtua Fighter 3, and Shenmu. I was wondering if anyone has actually seen this, used it, or even happen to have a copy.
I picked up a bit of info from here.
