How to enter Proto Palace Zone

Okay, so to enter Proto Palace Zone you must first head to the level select menu by pressing S, E, G and A in the SEGA logo in that order when it appears. If your did it right a ring chime will play. Then when Sonic, Tails or Knuckles appears on screen (depending on which character you choose) swipe up with two fingers. Now that your here, head to sound test and input the following code; 03, 03, 03, 0B, 10, 10, 10, 04. If you hear ring chime again, it worked. It's also best to enter Debug mode (here's the code incase you don't know it: 01, 09, 09, 02, 01, 01, 02, 04) as the level is (intentionally) unfinished and you can fall into a pit if your not careful.
