     Driver by Bryan McPhail and David Haywood.
 
     Todo:
-        Sprite priorities aren't verified to be 100% accurate.
-        There may be some kind of fullscreen palette effect (controlled by bit 3 in priority
-        word - used at end of each level, and on final boss).
-        A shadow effect (used in level 1) is not implemented.
+        * Sprite priorities aren't verified to be 100% accurate.  
+		  (Addendum - all known issues seem to be correct - see Sprite Priority Notes below).
+        * There may be some kind of fullscreen palette effect (controlled by bit 3 in priority
+          word - used at end of each level, and on final boss).
+        * A shadow effect (used in level 1) is not implemented.
+
+	Sprite Priority Notes:
+		* On the Imperial Science Museum level at the beginning, you fly behind a wall, but your 
+		  shots go in front of it.  This is verified to be correct behavior by Guru.
+		* There's a level where the player passes through several columns in a building and the 
+		  player goes behind every 2nd one. That is correct as well.
+	    * There is a fire hydrant with an odd-looking spray of water on various levels.
+		  If you drop the hydrant in front of an enemy (a tank, for example), the priorities are 
+		  wrong.  This is actual PCB behavior.  Also, the strange-looking water spray is correct.
+
+	Alpha Blend Note:
+		* There are semi-transparent round spots around your plane while fighting the final boss.
+		  These are correct.
+	    * The final boss shoots a blue beam downwards during the battle.  This should have alpha.
+		  It fades in to blue, then fades out to nothing again after a few seconds (Guru).
+		  (Potentially related to note above about bit 3 in priority word)
