Tested with: Lunar Magic 3.11, PIXI 1.2.14, SA-1 1.32, Snes9x 1.60. Very nice (and dangerous) variation of the original Blargg. I wish there were some defines to more easily customize some properties (like the Blargg's speeds, the timers for the various phases, etc.).
Note that both the Blargg and its projectile use palette F, rather than palette A.
