Sega Mega Drive Ultimate Sonic Collection - Sonic 1, 2, 3 & Sonic & Knuckles

90’s Retro Sonic Collection

Up for sale is the ultimate Sega Mega Drive Sonic the Hedgehog collection. This is a must-have expansion bundle featuring the complete 16-bit Sonic history, including the legendary lock-on technology cartridge.

All cartridges have been cleaned, fully tested, and are working flawlessly.

WHAT IS INCLUDED:
• Sonic the Hedgehog 1 (Standalone Cartridge)
• Sonic the Hedgehog 2 (Complete in Original Box)
• Sonic the Hedgehog 3 (Complete in Original Box)
• Sonic & Knuckles (Special Pass-Through Lock-On Cartridge)

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.

Price: €180. On pen to readable offers, no swaps.
