+/***************************************************************************
+
+ Astro Fighter hardware
+
+ driver by Lee Taylor 28/11/1997
+
+ Games supported:
+ * Astro Fighter (3 sets)
+ * Astro Battle (2 sets)
+ * Astro Fire
+ * Astro Combat (2 sets)
+ * Super Star Battle
+ * Tomahawk 777 late version with changed game play
+ * Tomahawk 777 early version
+
+ Notes:
+ * Astro Battle added by HIGHWAYMAN with help from Reip.
+ 2 sets, 1 may be a bad set, or they may simply be different - don't know yet.
+ protection involves the eprom datalines being routed through an 8bit x 256byte prom.
+ it *may* have a more complex palette, it needs to be investigated when i get more time.
+
+ * Astro Fighter set differences:
+
+ The differences are minor. From newest to oldest:
+
+ Main Set: 16Kbit ROMs
+ Green/Hollow empty fuel bar.
+ 60 points for every bomb destroyed.
+
+ Set 2: 8Kbit ROMs
+ Blue/Solid empty fuel bar.
+ 60 points for every bomb destroyed.
+
+ Set 3: 8Kbit ROMs
+ Blue/Solid empty fuel bar.
+ 300 points for every seven bombs destroyed.
+
+ * I know there must be at least one other rom set for Astro Fighter
+ I have played one that stoped between waves to show the next enemy
+
+ Known issues/to-do's:
+ * Is Astro Fighter supposed to have a blue background???
+ * Analog sound in all games
+ * Verify DIPs for clones
