In this one I retouched also the music selection screen and the secret ending.
Also, a few tiles were corrected (blue pixels on smoke, the blonde's head when scolding the pilot after a crash)
I don't recall any mention about inverted shades, but I noticed and corrected some on the ground when appropriate (i mean all stages but one must be light color on road, dark on field..only one -i don't recall which one- in the arcade has light-light pattern)
