http://bootleggames.wikia.com/wiki/Virtua_Fighter_2_VS_Tekken_2I have four copies, so if anyone here would like one, please PM me. I will sell them for $18 shipped, and that includes tracking worldwide. With no tracking, I can do $17 shipped. If there is interest, I will take pictures. These are originals, not reprints.
