Cheats in Modern Re-releases: Sonic Origins
The classic button codes do not work in the 2022 Sonic Origins compilation. Instead, SEGA has integrated these features into a modern progression system.
How to Unlock Cheats in Sonic 3 Origins
In Sonic Origins, you unlock classic features by playing the game and spending coins.
- Anniversary Mode: This default mode has a widescreen display and infinite lives, which is a built-in cheat.
- Earning Coins: You collect coins by completing missions and playing the game.
- Unlocking Debug Mode and Level Select: You must spend your hard-earned coins in the in-game Museum to purchase Debug Mode and Level Select for each game.
- Easy Chaos Emeralds: Anniversary Mode allows you to retry Special Stages by spending one coin. This makes getting all Emeralds much easier.
Active Cheat Codes for Sonic Origins
Sonic Origins does have sound test-based cheats that function similarly to the classics. Once you have Level Select unlocked, you can use these.
For Sonic 3 & Knuckles in Sonic Origins:
- Level Select: Use the menu unlocked via the Museum.
- Super Sonic Code: In Sound Test, play 04, 01, 02, 06. Collect 50 rings and jump.

The Definitive Classic Cheat Codes
For the original Genesis experience, either on the classic hardware or via emulation, these codes are your key to ultimate power. They were created by the original developers at Sonic Team and are the foundation for all secrets.
Level Select and Sound Test
The Level Select cheat is your gateway to exploring every zone. It also unlocks the Sound Test menu, which is required for more advanced cheats.
How to activate Level Select on the original Genesis:
- Start the game and wait for the title screen.
- As soon as you see Sonic, press Up, Up, Down, Down, Up, Up, Up, Up.
- You will hear a confirming ring chime.
- Press Start to go to the main menu.
- A new “Sound Test” option will appear. This is your Level Select menu.
An alternative method involves in-game actions. In Angel Island Zone, hang from a swinging rope. Press Left, Left, Left, Right, Right, Right, Up, Up, Up. You will hear a ring. Pause the game and press A to return to the title screen. The Sound Test option will now be available.
Powerful Debug Mode
Debug Mode is arguably the most powerful tool. It allows you to place any object in the game world, from rings to enemies.
How to activate Debug Mode:
- First, you must activate the Level Select and Sound Test as described above.
- From the main menu, enter the Sound Test.
- Play sound effects 01, 03, 05, 07 in that exact sequence.
- You will hear another ring chime confirming success.
- Now, select any level to start. You have activated Debug Mode.
How to use Debug Mode in-game:
- Press the B button to transform into an object and fly around the level freely.
- Press the C button to cycle through a list of objects like rings, monitors, and enemies.
- Press the A button to place the selected object into the level.
Getting All Chaos Emeralds and Super Forms
There is no single code that instantly grants all Emeralds. However, Debug Mode makes it simple.
How to get all Chaos Emeralds with Debug Mode:
- Activate Debug Mode and start any level.
- Press B to enter object placement mode.
- Cycle with C until you find the “Super Stars Monitor”. It looks like a power-up monitor with a star on it.
- Place and break seven of these monitors. Each one grants one Chaos Emerald.
To become Super Sonic, collect the seven Chaos Emeralds as described. Then, simply collect 50 rings in a level and press the jump button while in mid-air.
The Real “New” Cheats: Fan Mods and PC Ports
If you are seeking truly new content, the fan community is where the action is. The most celebrated project is Sonic 3 A.I.R. (Angel Island Revisited). This is a fan-made PC port that is considered by many to be the definitive way to play today.
Sonic 3 A.I.R. includes a comprehensive built-in cheat menu. It allows for easy toggling of infinite abilities, character swapping, and extensive gameplay customization. This project represents the evolution of cheating, offering players unprecedented control over their gaming experience.
Pro Tips and Common Mistakes
Using cheats can be incredibly fun, but there are some things to keep in mind.
Expert Tips to Enhance Your Gameplay:
- Use Debug Mode to practice difficult boss fights or explore hidden areas you missed.

- Do not expect the original Genesis button codes to work in Sonic Origins. They will not function.
