Sprites from different games on the NES

[Davy Jones]

I deleted him on purpose because it's just a duplicate without black. Everyone can delete this colour from the palette in a few seconds and I wanted to save as much space as possible.

In the original developers did not have rum black outline sprites, because he, and so the background is black.

Yes, I left the other boss duplicates because the versions without background have still some black parts left (I guess you tile-ripped them, huh?).
