+
+ 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
+ * Space Fighter Mark II (2 sets)
+ * Saturn: Space Fighter 3D
+ * 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
+
+ * Saturn: Space Fighter 3D is basically Space Fighter with extra game modes.
+ It's not 3-dimensional. The game modes are: Storm, Sweeper, Scramble.
+
+ Known issues/to-do's:
+ * Analog sound in all games
+ * satsf3d color prom is not dumped, using the one from spfghmk2 instead
+ (it looks good compared to photo)
+
+ About Colours:
+ * It was fairly common to have wiremods on these PCBs to change the
+ background colours, this is why you see Astro Fighter and Tomahawk
+ games with both Blue and Black backgrounds. By default MAME
+ emulates an unmodified PCB, you can enable the hacks in the DRIVER
+ CONFIGURATION menu.
+
+ B&W cabinet versions of the Space Fighter games also exist.
+
+ Versions of Tomahawk using the Astro Fighter PROM have been seen,
+ see notes in ROM loading.
