Ok, I've actually kinda replicated the effect with SPASM and this is the result.
(I've tested it on a different level btw)
As you can see I changed the things a bit. First of all, I've let some colors as the original, for example, a red, a yellow and a green. Even if I know the shadding effect looks really weird, that's the only way to recognize certain sprites (as the current egg's colors, which are impossible to recognize being black at all, or piranha plants) Yellow and red are also necesary to see properly the star counter on-stage (for displaying the actual numbers instead of a big black empty dot) Also, the effect seems to dissapear when getting the goal at the end of the level (not a big problem imo)

It would be cool to bring out a color like with the DK tie, for example the Baby Mario's cap or Yoshi's shoes. But I guess it's not that easy to manipulate palettes to get that result.
Actually this is possible, but it's needed to edit the Yoshi's graphics a bit, because colors are weirdly distributed on both Yoshi and Mario.
