Originally, Sonic 1 when locked onto Sonic & Knuckles would allow you to play as Knuckles the Echidna in Sonic the Hedgehog! However due to time constraints and color palette issues it was Scrapped and Blue Sphere was added in it's place. This Rom hack restores the original functionality allowing you to play as Knuckles in Sonic the Hedgehog, complete with Gliding, Climbing up walls, and Super Forms. Dr. Robotnik awaits in his base for the legendary guardian of the Master Emerald and Angel Island!
