Well, I found a copy of the Tri-stat dX system PDF elsewhere (since Googling it hits an Angelfire site with it before that DriveThruRPG site), but I do see people talking about a "fast play" PDF for BESM 3e, but the only links I can find point to the defunct Guardians of Order site or another site that is now claimed by a domain squatter.
And I wouldn't throw torrent and free into the same sentence without quotes around the latter, unless you're talking about something like Linux.
