I was playing sonic 3 and knuckles and I did the cheat to get a yellow super emerald why isn't there a yellow chaos emerald and what does the yellow super emerald do? Thanks.
The yellow emereald is just an extra bonus stuck in there because it was possibly going to be used for some reason and then wasn't and instead of removing it, they just leave it in to give those that look for bugs something to do possible.
