+Galaxia by Zaccaria (1979)
+Also released in several regions as "Super Galaxians".
+Set regions are unknown, so all are currently named Galaxia.
+
+Taken from an untested board.
+
+1K byte files were 2708 or equivalent.
+512 byte file is a 82S130 PROM.
+
+This is not a direct pirate of Galaxian as you might think from the name.
+The game uses a Signetics 2650A CPU with three 40-pin 2636 chips, which are
+responsible for basic sound and some video functions.
+
+Other than that, the video hardware looks like it's similar to Galaxian
+(2 x 2114, 2 x 2101, 2 x EPROM) but there is no attack RAM and the graphics
+EPROMS are 2708. The graphics EPROMS do contain Galaxian-like graphics...
+

+
+Astro Wars (port of Astro Fighter) is on a stripped down board of Galaxia,
+using only one 2636 chip, less RAM, and no PROM.
+
+Manual and Schematic for Galaxia can be found at:
+http://www.zzzaccaria.com/manuals/SuperGalaxiansTechnicalManual.zip
+http://www.zzzaccaria.com/manuals/GalaxiaSchematics.zip
+
+The manual for Astro Wars can also be found at:
+http://www.opdenkelder.com/Astrowars_manual.zip
+
+HW has many similarities with quasar.c / cvs.c / zac2650.c
+---
+
+TODO:
+- correct color/star generation using info from Galaxia technical manual and schematics
+- add sound board emulation
+- improve bullets
+- accurate sprite/bg sync in astrowar
