When you initiate Sonic The Hedgehog 1, 2, 3, Sonic And Knuckles, Sonic 3D blast, Dr. Robotnic's Mean Bean Machine, or Sonic Spinball, the screen states that it is logging the game data. That indicates the game is logging in that you have initiated that game once. After initiating a game fifty times, it no longer shows that game-logging screen. It stops the logging sequence screen from ever starting a game again and from then on, just starts the Genesis program itself. To unlock a hidden game, you must start a particular Mega Collection game fifty times, continually pressing Z to exit it, then enter into the game repeatedly. Some hidden games do not necessarily require that you start up fifty times, but you eventually need to do so to unlock all the hidden games.
Flicky: Start Dr. Robotnic's Mean Bean Machine before reaching 50 times. Blue Spheres: Start Sonic The Hedgehog about 18 to 21 times. Sonic 3 And Knuckles: Unlocked sometime in the process of starting Sonic 1, Sonic 3, Sonic And Knuckles, and Sonic 3-D Blast fifty times. Knuckles In Sonic 2: Unlocked in the process of starting Sonic Spinball and Sonic 2 fifty times. Ristar: Start all games (Sonic 1, 2, 3, Sonic & Knuckles, Sonic 3 and Knuckles, Knuckles in Sonic 2, etc.) fifty times.
In sonic the hedgehog green hill zone there are some items like the shields and invincibility thing and speed shoes only in sonic 1.
Get stage select and use debug and supersonic codes then select any stage. First, use debug mode to transform into a ring. Keep pressing X until you have at least 50 rings. Next, transform into a box and press x again to copy it. Then, transform into supersonic and hit the box. It should send you back and you should still be supersonic. This time, his abilities should be exactly like sonic and should NOT run on any rings! When you finish a stage, the sign should be completely supersonic and he would NOT transform back to regular sonic. NOTE: This does NOT work on Flying Fortress!
This strange encounter and the fastest you'll ever see a character going in a 2D video game requires the debug code with either Sonic or Knuckles. At the very end of act 3 just before the boss fight, there is an area in which you can snap into debug mode, move your character down in debug mode to the very bottom [screen location of close to 0780 for the last four]. Exit debug. You should start falling and accelerating to a very high speed. After nearly 15 seconds, you'll be going up mysteriously. This occurs when you reach 128 pixels per frame [and the screen is only 224 pixels high!], which means that in 2 frams, you'd go one full screen plus extra! It works best if you jump off the edge of a cliff while holding X.
If you have lost alot of lives on Final Rush, Final Chase, Security Hall or levels like that, just go to Pumpkin Hill, select any mission. Fly over the thin bridge to right where you got Shovel Claw. Dig inside the circle, then quit and do it again. I told you it's cheap. But it works! And to make it go faster, sometimes you can dig uo 2 1-Ups at the same time.
Save your Sonic Mega Collection data on a memory card with data saved for Sonic Adventure 2: Battle and Blue Sphere and Flicky games will be at the games menu.
On Sonic 2 and 3 you can have a friend be Tails. Tails can't fly on Sonic 2 but he can on Sonic 3 and carry Sonic. Another good thing about Tails is he can't get killed and he can beat up bosses if Sonic is about to get killed.
(This tip also works in Sonic 3 & Knuckles) Beat the game once with any file. Go back to the file you beat the game in and select Stage 1. Go to the lowest area at the beginning where there's a Monkey Badnic and rocks on the wall. Use a Spin Dash on the rocks to break them down and go into a secret area with a giant Ring. Leap into the giant Ring to go to a Specail Stage. Collect all the blue spheres and obtain the Chaos Emerald. When you get the Chaos Emerald, and you're back at the first level, push Z and go to Game Title to restart the game. Repeat this process until you have all the Chaos Emeralds. After you get all Chaos Emeralds, you will either become Super Sonic or Super Knuckles(You can't be Super Tails yet). Go back to the file where you've gotten all the Chaos Emeralds and go to Stage 7. If you're Sonic or Tails, you will have to watch a cutscene showing Knuckles trying to hide the super giant Ring. Push a switch to open a secret area. If your Knuckles, all you need to do is walk in. Leap into the super giant Ring and jump onto a Chaos Emerald. You will have to go through another 7 Specail Stages to get the Super Emeralds. Get all the Super Emeralds to become Hyper Sonic, Super Tails, or Hyper Knuckles.
Level select After the Sega logo fades and Sonic starts to appear, and before the screen flashes white, quickly press Up(2), Down(2), Up(4). If you entered the code correctly, you will hear a chime. Press Up at the title screen to access level select and sound test options. Debug mode Enable the "Level Select" code. Hold B, then press Start when selecting the desired level. Secret level Enable the "Level Select" code and select the sound test option. Play sounds 1, 3, 5, 7 (in order). Highlight "Special Stage 2", then hold B and press Start. Extra lives Set off the first alarm on the first level of the Launch Base Zone. Wait in the middle of the alarm and perform Spin-Dash attacks on the Flybots. The value of the Flybots will eventually increase to 10,000 points as they continue to attack. Accumulate points and lives at this location. Sonic And Knuckles music In the 2nd Zone and 3rd Act, before fight Dr. Robotnik, allow your character to almost drown, then put your head back up in air (touch the starpost but down jump in it). Speed boost To instantly get a speed up, jump when Sonic is a little over halfway on the loop. Quick Goodies At the start of Angel Island, kill the monkey in the tree and jump on the first gray rock to reveal a bumper spring. Bounce up into the tree, and using the bumper spring hidden in the tree, bounce left to land on the moving platform. The platform will take you to a ring bonus and lightning shield power-up. Using the spring in the tree again, bounce right to land on ground with spikes and a RhinoBot. Jump past these to collect the fire shield. Many rings On Act 3 of the Icecap Zone, turn into a ball at the end before you reach Robotnic and fly off a ramp onto a purple trampoline. Look up to see a large number of rings. Bounce high enough to find another whole set of rings. Go to the right far enough to find a big ring.
Level select Use the sound test selection on the options menu. Choose sounds 19, 65, 9, and 17 (in that order). If you entered the code correctly, you will hear a chime. Hold X and press Start. Hold B and press Start when Sonic and Tails appear at the title screen. Debug mode Enable the "Level select" code. Use the sound test selection on the options screen. Choose sounds 1, 9, 9, 2, 1, 1, 2, 4 (in that order). If you entered the code correctly, you will hear a chime. Select any starting level, then hold B + Start until game play begins. Screen coordinates will appear instead of a score and the number of objects displayed will appear instead of the time remaining. Use one of the following controller actions to enable the corresponding debug code. Note: This code may only be enabled when playing as Tails alone. Play as Super Sonic Enable the "Level select" code. Use the sound test selection on the options screen. Choose sounds 4, 1, 2, 6 (in that order). Start a stage, collect 50 rings, then jump to transform into Super Sonic. Mega Sonic Collect fifty rings and jump after becoming Hyper Sonic for even more speed and higher jumps. Infinite speed shoes Begin game play in two player vs. mode and hit as many item boxes as possible until you get the speed shoes. Then, intentionally lose your life while you have them (getting squashed is the easiest way). You will return to the start of the level or the last Star Post that you hit, but you will now have the speed shoes in effect for the rest of the stage. Super Sonic sign Get all of the Chaos Emeralds and transform into Super Sonic. Try to have at least fifty rings when you finish the level. After completing the level, run off screen and wait until the end-of-level sign shows Sonic. When it does, transform into Super Sonic. The sign will show Super Sonic for one second, then show blue Sonic again. Starry Super Sonic Get all the Chaos Emeralds and collect fifty rings, but do not transform into Super Sonic yet. Find an invincibility monitor and spin (do not jump) into it. Then, transform into Super Sonic. If done correctly, the stars will surround Super Sonic until he runs out of rings and transforms back into blue Sonic. Note: This does not improve Super Sonic's performance. Wing Fortress shortcut In Wing Fortress, move with some rings as far to the right as possible without climbing. When blades appear to block your way, hit them. As soon as you are invincible, walk through them. Jump on the platforms to the right and half the level will be completed. Bonus points For extra points, pass any zone in a certain amount of time. For the best bonus, enter the "Debug mode" code. The clock will stop and you will always score a 50,000 bonus. Time Points 0:30 50,000 0:45 10,000 1:00 5,000 1:30 4,000 2:00 3,000 3:00 2,000 4:00 1,000 5:00 500

Directly to the right of the Madmole is a pulley mechanism that takes you to the next level above by pushing Down on it repeatedly. Grab a hold of its left handle, but instead of pushing down, push the follow sequence while on it: Left(3), Right(3), Up(3). If you entered the code correctly, you will hear the sound of a chime.
