So you want NES style sprites, huh?
Not that simple. You have simplistic-style limitations you must abide if you want to make it look genuine.
1. You can only use these colors.

2. Unless it's a background sprite, it can only use 5 colors (counting transparency which is 0E and 0F).
3. Background sprites can only use ten colors (transparency cannot be used in backgrounds).
4. Non-background sprites cannot be bigger than 32x32.
With all that said and done, you come out with a sprite.
