TODO:
-- speed is wrong for all games. needs investigation, interrupt related?
- real hardware video of Astro Wars can be seen here: youtu.be/eSrQFBMeDlM
-- correct color/star generation using info from Galaxia technical manual and schematics
+- go through everything in the schematics for astrowar / galaxia
+- video rewrite to:
+ * support RAW_PARAMS, blanking is much like how laserbat hardware does it
+ and is needed to correct the speed in all machines
+ * improve bullets
+ * provide correct color/star generation, using info from Galaxia technical
+ manual and schematics
+ * provide accurate sprite/bg sync in astrowar
+- what is the PROM for? schematics are too burnt to tell anything
- add sound board emulation
-- improve bullets
-- accurate sprite/bg sync in astrowar
