FF6 Steam Version

I'm actually kind of stunned they used .bmp for the sprites instead of .png.  bmp's aren't compressed, png's are.

Anyway, you can probably use all 255 colors; it's part of the file format itself.  I'm actually curious as to how the transparent color works.  Is it the first color in the palette or the color in the top left corner of the sprite?

I assume it´s the green background but i could be wrong
