Yikes, it's weird that so many people think STAG just means "porn" disks. No, no, no! The "STAG" disks said STAG very cleary (and very noticibly) during loading. They were made up of looping video clips from porn.
So they ARE porn disks then. Eh?
I too have encountered many of these on old 'zeraw'
CDs, and they didn't contain anything else but THAT.
So quit talking around the subject! They are porn, period!
