Dont know much about genesis programing, but maybe the glitched sprites happen due to the game trying to load a unexistent sprite, meaning that possibly Super/Hyper Knuckles was originally supposed to have unique sprites. Am not sure about the palette but it could be leftover code from Super Sonic or Knuckles was intended to glow yellow, just a wild guess.
