+- Colors are not right. In zerohour P1 score should be white, the top score green,
+  and "TOP" should be magenta. How is this determined? It's as if only the top part
+  of the screen has this exception. Sprite colors look ok.
+- Some graphical problems in both games
+- redclash supports more background layer effects: white+mixed with other colors,
+  used in canyon parts and during the big ufo explosion
+- Player bullets: should be 8*2px magenta in zerohour. It's weirder in redclash:
+  1st half of the screen 4*2px red, 2nd half 8*2px yellow.
