ZloolS | Sonic 3 and Knuckles (Sega Genesis) - Part 2 @ZloolS | Uploaded 14 years ago | Updated 22 seconds ago
Sonic the Hedgehog 3 and Knuckles for the Sega Genesis.
Sonic & Knuckles utilizes "lock-on technology" that lets the cartridge plus the Genesis/Mega Drive access data from Sonic the Hedgehog 2 and Sonic the Hedgehog 3 so that elements of both Sonic & Knuckles and the locked-on game are combined. To play these combined games, the hatch on top of the Sonic & Knuckles cartridge can be flipped open and the second game placed inside.
