Sonic 3 & Knuckles - Get Blue Spheres - Unused Stage Made Easy

Ever tried to do this rather difficult map (unused), and failed numerous times? Well there is an easier way, just simply make your way to the centre (you normally finish here) and do the entire "spiral" in reverse.

LEVEL SELECT:
Sonic 3 & Knuckles' level select is performed similarly to that of Sonic & Knuckles: grab one of the rope swings in Angel Island Zone and press Left, Left, Left, Right, Right, Right, Up, Up, Up. After the ring sound plays, press Start then A to return to the title screen.

DEBUG MODE:
At the title screen, "Sound Test" will be available below "Competition". This will open up the level select menu (with a sound test at the bottom-right). Press C on this menu to change your character (00 is Sonic & Tails, 01 is Sonic, 02 is Tails, and 03 is Knuckles).

CODE FOR UNUSED STAGE:
First enter the level select and Debug Mode cheats and then set the Sound Test selection to 07, then press A + Start while selecting "Special Stage 1" to access the eighth Special Stage from Sonic 3, or "Special Stage 2" to access the eighth Special Stage from Sonic & Knuckles.
