+TODO: Cosmic alien colors in-game are wrong;
+See http://www.andysarcade.net/pix/dumping/cosmic/
+The colors for the text on the "titlescreen" (with the 1979 universal
+copyright), and the status bars are correct in mame, but the sprite colors
+for the aliens when in formation are clearly wrong as compared to andy's pics.
+The shots on andy's page are the correct ones, as the aliens when 'breaking
+formation' in mame change to colors which match the ones in his pictures.
+There is probably a missing bit for color prom banking or for
+forcing all sprites on a row to have an added blue component.
