Super Sonic and Hyper Sonic in Sonic 1

Super Sonic and Hyper Sonic in Sonic 1 is a ROM hack of Sonic the Hedgehog (1991) where you unlock and control Super Sonic and Hyper Sonic within the original game structure. You collect all seven Chaos Emeralds and reach fifty rings to transform. Super Sonic moves faster and jumps higher, while Hyper Sonic triggers a screen flash that defeats nearby enemies. You can activate the transformation manually and return to normal form when needed. All original zones, such as Green Hill, Marble, and Scrap Brain, remain playable with the added power mechanics. This version also includes updated sound effects and minor animation enhancements tied to transformation states.
