Knuckles In Sonic 1

Introduction: Knuckles in Sonic 1 is an advanced ROM hack of the original Sonic the Hedgehog for the Sega Genesis / Mega Drive by Stealth. It effectively answers what Sonic 1 might have been like if the Sonic & Knuckles lock-on cartridge had supported the first Sonic game.

Gameplay & Mechanics: Knuckles retains his signature abilities, including gliding, wall climbing, and the Spin Dash. His lower jump height and different movement options significantly change navigation through the Sonic 1 stages. The hack also supports Super Knuckles after the Chaos Emeralds have been obtained.

Key Features:

• Knuckles fully integrated into the Sonic 1 engine.
• Spin Dash, gliding, and wall climbing implemented.
• Super Knuckles functionality available after collecting the required Emeralds.

This is more technically ambitious than a simple sprite replacement and reproduces much of Knuckles' later Genesis moveset inside Sonic 1.
