Several areas in Sky Deck 3 have different lighting. For example, the walls right behind Knuckles at the start of his level are almost completely white in SADX. I originally thought this was a palette selection issue, but apparently it's a different light direction. It could be that light direction in Sky Deck rotates together with the ship's tilt, or is just different from the direction specified in SL_60B.BIN (if the mod loads that).
