Sonic and Knuckles
  Sonic and Knuckles is the 6 zone rip-off from Sega. The idea is if you buy this then you can go and play Sonic 3 as knuckles and then once you finish Sonic 3 you can play all of the Sonic and Knuckles stages. But people have hacked into Sonic 3 and found that the Sonic and Knuckles levels are in the Sonic 3 just completely covered in several colours only.
   But Sonic 3 is not the only game where you can play as Knuckles. You can also do it in Sonic 2. However Knuckles seems to jump lower than normal. Sonic 2 is extremly easy as knuckles except the last boss on Metropolis Zone is almost impossible. Mainly because you can't jump in the air very high so you can't eally jump over his ballons.
