Those who saw Sonic Mania as the nostalgia-filled love letter to their childhoods might remember the days where Up Down Left Right or 19, 65, 09, 17 were keys to unlocking hidden secrets within the classic Sonic games. It appears that the 90s styled cheat codes have returned for Mania, as discovered by some players. If you start up a Mania Mode game, then enter Debug Mode, and hold Y/Square when selecting a no-save file, you can input the following in the Sound Test menu:

0 0 0 0 6 2 1 4 - Disables the Super theme music
9 0 0 1 - Gives Sonic the Drop Dash, Insta Shield, and Peel Out all at once
3 3 3 1 9 7 9 0 8 1 1 - Changes all freed animals into Squirrels
4 1 2 6 - Gives all Chaos Emeralds
1 9 9 2 1 1 2 4 - Gives you unlimited continues
2 0 1 8 0 6 2 3 - Forces gamemode into Encore Mode
2 0 1 7 0 8 1 5 - Lets you fly like Super Sonic in normal stages

All of these numbers reference certain special dates, as well. The unlimited continues code is the date of the EU release for Sonic 2, the Super Sonic Flight code is Mania's original release date, force Encore is Plus' release date, 4126 also gave you every emerald in Sonic 2, there's an over 9000 meme, and 1979 08 11 is Stealth's birthday.

I remember the debug menu in sonic2. I hated and never tried a second time. I never did feel right cheating in games. This debug menu was very buggy as well. I’m glad that this has been included.

Now that I think about it (ntitai?), I did cheat at contra with the kanomi code. I justified that by beating it without cheats first. My personal best with 30lives is beat the game in 20minutes no continues.

Is the fly around in normal stages code right? It's the only one I can't get working.

It should also be mentioned that if you select a number on the sound test then select the blue sphere special stage while holding the same button you used to enter the level select, you can choose which one of the 32 stages from mania mode to play. (Though I dunno if there is a way to select a chaos emerald special stage but hope someone finds it too)

Aww, how cute!
2 0 1 7 0 8 1 5 is the release date of Sonic Mania!

and 4 1 2 6 is the same cheat code used in Sonic 2 to unlock all the chaos emeralds!

awww they discovered them too fast the team thought it'll be a great challenge for players to find them.
Also yeah, the master control code is a reference to DBZ(Over 9000!!)

This is all I ever cared about in this game. I thought it was a little limiting only getting one type of power up. The DBZ reference actually does make sense too haha

I don't think it was too fast myself. I typically like playing around with cheat codes after I've beaten a game. Since it's been about 6 months since I've even booted it up, this seems the perfect time to try out Plus mode and the new unveiled cheats.

 

[BlueFox gui]

i guess they did that because we could already do that and MORE with Mania Mod Loader which has a cheats tab XD

 

[Song of storms]

Did they just make an over 9000 cheat code

Oh my gosh, so close!

It was the best, especially if you conveniently place 50 rings before the final battle and face Metal Sonic before that big Robotnic robot as you can always grab some back (or you could just debug and move to all the stage ends).

Sonic's 27th anniversary?

 

[BORTZ]

This is pretty cool. Cheats and debug mods are tons of fun once you finish the game legit.

Oh, you mean that disaster party that ended up in soup because they didn't hire the correct audio engineers?

Eh, the day was still Sonic's birthday, even if the birthday party kinda got ruined. ¯\(ツ)/¯

 

[WeedZ]

I still have those sonic 2 codes burned into my brain

 

[Sonic Angel Knight]

Sonic's 27th anniversary?

Yeah, let's announce a game celebrating sonic's 25 anniversary, then release it a year later, and then release dlc for the game a year later again to celebrate 27 years. What is with companies celebrating their anniversaries by not releasing games "THE YEAR THE ANNIVERSARY IS IN"

Clean up the rabbit hole folks.

Probably better to get a decent game a year or two later, than getting a broken mess the same year the anniversary is in (*cough* Sonic '06 *cough*).
Well, it doesn't look like the delay helped Sonic Forces in any way, though…
It's like they didn't know the 25th anniversary is coming and couldn't start the development earlier?
