Sonic & Knuckles for Mega Drive was released on October 18, 1994 in Japan.

Sonic & Knuckles utilizes 'lock-on technology' that lets the cartridge plus the 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.

This game is known as "Sonic 3 & Knuckles" when locked on with "Sonic the Hedgehog 3".

This enables the Debug code, you should hear a ring chime if the code is entered correctly. start the selected level with A+start.
To get all 7 Chaos Emeralds, input this code the same way: 01 06 07 07 07 02 01 06
You should hear the Emerald chime. Note: this code may not work without the Debug code
