It's not *mine* I stole it from http://www.biglist.com/lists/stella/archives/200403/msg00260.html (R.Mundschau) who independantly invented it. It was also discovered by Manuel, who noticed it in Battlezone (I think).
Actually, Mr. Mundschau's version does have a significant advantage over Battlezone. By using a lookup table for the HMxx value rather than calculating it with four shifts, it fits (almost) entirely into one scanline.
