I'm going to be honest here Boy as by the looks of it, you're putting effort into it. All the spriters aren't TRUE gb coloured. GB coloured uses a palette and only has a maximum of 3 colours (4 on large sprites) per sprite including black.I hope this helps you. I shall see if I can find the palette for you. Good luck with this as due to GB being a simple style, this project is possible!
they're not very good but here are the sprites of using the windwaker
do you need any others?
I made a hud of the hookshot, but it's not very good
well, it's not perfect because the hookshot is almost as big as linki was too lazy to make a full bitmap, but the editing will be easy
