is there some type of way to go super sonic if you restard the game with all emeralds?
That was the super nice-to-have feature on the list, but got dropped… Data change (increase speed) would probably be cheap, and it’s super cheap to recolor Sonic’s blue in yellow (as in the original game), but in reality you’d need dedicated sprites for most poses due to hair spikes change, and that would go out of budget (unless it was distributed on a separate cartridge!)
