Sonic Mega Collection Codes -

Unlocking hidden games:
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 And Knuckles, Sonic 3 And Knuckles, Knuckles In Sonic 2, etc.) fifty times.

Kill yourself until you have one life remaining. Then, locate the barrels in the Toxic Caves stage. Jump in a barrel and move toward the wall opposite the emerald. Jump out of the barrel and intentionally lose a life while returning to that barrel.

Special Zone entrance:
You can almost always have the Special Zone entrance open (the giant ring next to the sign at the end of level Acts 1 and 2) by not losing your rings. If you do lose your rings, when you pass a checkpoint, intentionally die, then continue through the level without losing any rings. This works about 80% of the time.

Sonic The Hedgehog 2

Level select:
Use the sound test selection on the options menu. Choose sounds 19, 65, 9, and 17 (in that order). A chime will confirm correct code entry. Hold X and press Start. Hold B and press Start when Sonic and Tails appear at the title screen.

Debug mode:

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.

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.

Unlimited 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

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.

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. When this is collected, Sonic can use the fire dash attack by pressing C(2).

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.
