To find them, one must enter any Sonic & Knuckles zone with all seven Chaos Emeralds, and jump into a flashing Giant Ring. These transport the character to the Hidden Palace, where the power of the Chaos Emeralds is transferred into large, grey emeralds. He can then jump onto one of the dull grey Super Emeralds and be whisked away yet again into a special stage. The Special Stages are identical to those in Sonic & Knuckles.
In Mushroom Hill Zone, there is one Giant Ring accessible to each character that always leads to a Super Emerald, no matter how many Chaos Emeralds have been collected. Collecting all 7 Super Emeralds unlocks Hyper Sonic, Hyper Knuckles, and Super Tails.
In Sonic Mania, the Super Emeralds make an appearance in their resting place in Hidden Palace, reached at the end of Lava Reef Zone Act 2 as Knuckles. Unfortunately, they have all turned grey and cracked, and are now completely drained of their power and thus can no longer be used.
