I figured out what to do about making the pieces smoother for Zillions-of-Games, which allows only a single fully transparent color instead of multiple partially transparent colors. It's similar to what I've done before in making pieces. While I might be able to automate this, I have been doing it manually following these steps in Ultimate Paint:
I open a PNG file.
With green (#00FF00) as the foreground color, I color the background green.
I make green the official background color and copy the image as a brush, which gives me a version of the image without the background.
I paste this brush to the center of a 48x48 grey (#808080) image.
I change anything colored #808080 to #00FF00.
I save it as a 256 color BMP image.
What this does is turn the partially transparent colors into shades of grey, which looks smoother than letting them turn into black, as they were doing with a simpler conversion. While the look may not be as ideal as what you can get with a PNG file on the web, it's probably the best I can do within the limitations of the graphics capabilities of Zillions-of-Games.
