|Fifth level, Sonic R|
|Level theme: outer space|
Radiant Emerald is the unlockable fifth stage in Sonic R. It is the only course which has to be unlocked, accomplished once you place 1st in all of the races on the Grand Prix mode. It is a magical rainbow course that swirls around planets through outer space! The ring gates here contain massive shortcuts, so use them to your advantage. It is the only track to contain no Chaos Emeralds and is the only track to play a different song if you are Super Sonic racing against all the unlockables.
