Intro
This guide will explain to you how to access the level select and debug mode in Sonic the hedgehog 3 & Knuckles.

The level select, (as the name implies) allows you to go to any level in the game, but it also allows you to play every sound and song in the game.

The debug mode allows you to go into any level in the game and add enemy's and obstacles to the level.

Lets start by showing you how to get to the level select first, since you need it to unlock the debug mode.
Level Select
In order to access the Level Select, You must first go to Angel Island Zone, Once you are there grab onto one of the swinging ropes Sonic hangs off of, They appear very early In the stage so this should be no problem, then press Left three times, Right three time, and then Up three times in that order, you should hear a ring sound being played, then press Start followed by pressing A and B or A and C, This should return you to the Title screen with seemingly nothing changed, but if you scroll down past Competition there should be a new option labeled Sound Test, selecting this option will take you to a level select as well as a sound test.

Here you can select and go to any stage in the game, if you press C the number under Angel Island zone will switch between 00, 01, 02, and 03, this number represents what character you will be when you enter a stage, 00 is Sonic and Tails, 01 is Sonic on his own, 02 is Tails on his own, and 03 is Knuckles, you may also notice that there are 2 Zones labeled Lava Reef, with there seemingly being 4 Acts of Lava Reef, Act 3 Will take you to the sequence leading up to Act 2's boss fight as well as the boss fight itself, and Act 4 will take you to Hidden Palace Zone, there are also Act 2's of Sky Sanctuary and The Doomsday Zone, Trying to enter Act 2 of Sky Sanctuary as Sonic, Tails, or Sonic & Tails will not work and wont do anything, But if you are playing as Knuckles it will take you to the Mecha Sonic boss fight, and entering Act 2 of Doomsday Zone will take you to the boss fight after Act 2 of Death Egg Zone, Act 1 can also not be entered as Tails on his own or Knuckles.
Debug Mode
From the level select, you can enter debug mode by going into Act 1 of Mushroom Hill and grabbing one of the pulley systems that you press down on while grabbing to go up, then input the same code you put while grabbing one of the ropes in Angel Island, Left Left Left, Right Right Right, Up Up Up, after hearing the ring sound again, Press A and C or A and B while the game is paused (press Start to pause), then after returning to the Title, go back to the sound test and hold A while selecting whatever stage you want to use debug mode in, you will now be able to use debug mode in whatever level you selected, and if you beat said level, you could play the rest of the game in debug mode!

while playing with debug mode unlocked, you can press A to flip gravity for you (you can still jump with C), and you can press B to enter debug mode, use the D-Pad to move freely through air or solid ground, while in debug mode you can press A to switch between a variety of items in the level you are playing in, such as rings, monitors, enemy's, and other elements in the stage, press C to spawn in the selected object, you can also press B again to leave debug mode.

it works for me but for some reason once i turn into an item i can't turn back into the character, so i guess debug mode doesn't work correctly in this version of the game.
