HOW THE LOCK-ON TECHNOLOGY WORKS (EXPLAINED):
The Sonic & Knuckles cartridge features a unique slot on top that allows you to combine your games physically:
1. Lock-on with Sonic 3: Combines both games to create "Sonic 3 & Knuckles"—the massive, definitive way to play the game with full save functionality and Knuckles completely playable!
2. Lock-on with Sonic 2: Unlocks "Knuckles in Sonic 2," allowing you to glide and climb through the entire second game.
3. Lock-on with Sonic 1: Unlocks the full standalone, endless "Blue Spheres" special stage puzzle game.
