Hey, I really appreciate your work! It is quite amazing to have all these sprites, especially the backsprites as well.
I have two questions about it:
1) Is there a resource on how to extract such sprites, so that someone could contribute? I would be very interested in that.
2) I noticed that certain sprites have a lot of empty space in them:
Is there a reason for it and a way to remove them? I'm thinking about use-cases in other areas and there this empty space is really annoying.
