If you put in Sonic 2, you get Knuckles in Sonic 2.If you put in Sonic 3, you get Sonic 3 & Knuckles.If you put in Sonic 1 or Sonic Classic 3-in-1, you get all levels of Blue Sphere (Press A+B+C on No Way screen).If you put in any game other than those listed, you will get one level of Blue Sphere (but not all games work).
Well it took me 3 or 4 trys to complete it, its just like any other level, get to the goal ring. Only after you complete it, you have to fight the boss Iblis phase 2. he's fairly simple.
The best place to play sonic 3 for free is retrogamer.com.you can also play sonic 2 and 1 there
Collect all the Chaos Emeralds, and beat the game normally with Sonic as the leader. You can only be Super Sonic in the true final boss (the extra boss). There is no cheat to make Sonic super in normal levels.
I will say Sonic's 1, 2, 3 but Sonic & Knuckles is tottaly awesome or Sonic Blast Dudes!
