High Score Competition Rules and Scoreboard-----------------------------
Game Name :   Kamizake  
ROM Name  =   kamikaze  
-----------------------------
I remember playing an Astro Invader at a local convenience store when I was a lad.  Apparently, Kamizake by Leijac was first (1979) in Japan.  There is a difference in the dip settings for points needed for extra life between these two versions, but aside from that I don't know if they differ.  Either way, let's use the kamikaze rom. Oh, and it uses "invaders" sound samples. 
This thread talks about the game a bit.  
Move left, move right, and fire.  Get in to the groove!
