Tip: If you place a moon, midpoint, or dragon coin through Map16, it will always respawn whenever you reenter that sublevel. It will not respawn if you add it through the Add Objects/Extended Objects window.
Changed scrolling of both BG and layer 3 to CONSTANT, CONSTANT, since it's supposed to be a giant background. Great job with this one. Reminds me a bit of the same trick I've used to make a giant background for one of my Kochobo Dourado 2 levels.
