How do you get hyper sonic in sonic 3 and knuckles

In order to be Hyper Sonic, you need all the Chaos Emeralds. Then, from Mushroom Hill Zone on, the giant ring you go in that starts the special stage will flash. If you get all the Super Emeralds (The Game Genie cheat for the Get Blue Spheres only needs one blue ball is ACGA-AA8T), Collect 50 rings and jump twice. If you are Sonic and he flashes different colors, you did this correctly. Do the same with Knuckles and he will be Hyper Knuckles. Tails can transform, but only with the Hyper Emeralds.
