Dodonpachi 252m Blackisto

New PB: 252,840,300
Done on 26 Mar 2017 using a Sega New Astro City cab running Mame.
Good loop1 scoring, with a very stupid mistake on boss 6 pattern 2 (I did too much damage to the boss) which caused a different final pattern that quickly killed me.
Loop 2 is so ugly that I didn't upload this run immediatly.
Was so angry at this loop2 that I quickly signed "BLL" instead of "BLK".
So if you think that this run is not from me. It's OK, cause the run is not nice ;-) I hope to quickly improve this PB.
