I have at the end of this Japanese VHS tape of the Garou Densetsu/Fatal Fury The Motion Picture this featurette with a live-action Terry Bogard (in a really bad wig) fighting some thugs, and some footage of the at-the-time newly released Fatal Fury 3.
Well, I uploaded that video to YouTube . . .
. . . I'm still don't get what the plot of all that live-action stuff is supposed to be!
