GCE Vectrex - Mr. Boston Clean Sweep Overlay 1.0.0

This overlay is based on the Libretro Clean Sweep overlay. I found a perfect scan of a rare Mr. Boston overlay and applied the subtle differences to it. The remainder of this collection can be found here. Since this is such a rare game, I felt that it was an injustice to be using the wrong overlay. I believe that this is as close as you can get to the real thing (and there are less than 10 in existence).  I only take credit for the modification to the original file and thank those in the community who contributed to what is already out there.
