Sonic 3 and Knuckles Glitches and Oversights - Hydrocity Zone

[@taids]

"what's life like using loopbacks on vertically wrapping levels?" "eh, it has its ups and downs"

[@abraveastronaut]

I'm glad you showed the boss music glitch working against both bosses. A lot of people assume it only works in Act 1 for some reason.

[@aperturius]

It's probably a space-saving measure, but it's also how they made more seamless levels where the screen doesn't have to fade to black between acts like in Sonic 1 and 2.

[@MegaMan52]

These Sonic 3 glitch videos of yours are really fun to watch! Can't wait for Marble Garden.

[@we11ee]

3:25 what do you have against hedgehogs crossing the border

[@jmiester25]

the bottom of hydrocity always scared me for some reason.....

[@IDGeek121]

Oh goodness. That last glitch has screwed me over so many times.

[@sosams]

In the last glitch, you can bypass Robotnik and end the act without being forced to softreset, but you need to: 1. Not open the animal capsule 2. Beat the boss, but only with Tails offscreen (it is pretty hard). If Sonic tries to beat the boss, the animal capsule will disappear and then be forced to drown.

[@nil8659]

You found a Parallel Universe in a non-Mario game! Great!

[@Schnort]

8:57 heyy great glitch considering i love the "knuckles encounter" music.

[@DevynProwerTF]

Once I glitched in hydrocity Zone because that animal capsule made me skip a boss fight!

[@NunofYerbizness]

3:01 From what I've found, not every level can have their loopbacks accessed, even with debug mode. What ones I can recall being accessible are; Angel Island Act 2 (Blue Knuckles only) Hydrocity Marble Garden Carnival Night Ice Cap Act 2 Launch Base Act 1 (You can visit Act 2's loopback technically, but it's very easy to get the game to unload the entire level to make room for the self-titled launch base) Flying Battery (November 3rd prototype only) Sandopolis Act 2 Lava Reef (November 3rd prototype only) Death Egg

[@mayaraoficial4310]

Hydrocity act 1 loopback

[@fatlol2389]

Did you know? When you finished hydrociry 1 with tails drowned, tails is nowhere to be seen in act 2

[@Gradient___]

9:32 Man...I remember doing that glitch so many times by accident and softlocking myself. It was pretty frustrating.

[@IvanFranco120]

I managed to trigger myself twice this glitch, but without even super sonic.

[@SyphistPrime]

I've actually stayed super after the boss before. I was never sure on how to reproduce it.

[@dededethesuperstarwarrior]

9:37 The capsule didn't load graphics correctly, Because the screen didn't locked on still, Once it locks-on, all tiles on the zone (i think) are cleared.

[@ArcadianMyrmidon]

I remember finding some of these glitches myself... but only a few since I never messed around with Super Sonic. It was so funny when I found the Sonic 3 music error... I never got to play S&K for YEARS afterward, so I never figured what the music was.....

[@cottagechskitty]

I am convinced that they created Hyper Sonic just to create glitches. :) No actually its that they added him without realizing the problems it'd cause

[@painco94]

if i remember well, in the last glitch when you hit the las button, if you reset thes savestate will be in marble garden

[@CffYT]

Another glitch with the act 1 mini-boss music is that it isn't playing the Sonic 3 mini-boss theme in the first place. It's playing the Robotnik battle theme for some reason.

[@battleonfan1]

The sewer part is actually an unfinished level called "Underwater Palace". Sega had a due date for the game and it was almost up so they left out "Underwater Palace" and now it is just a mess.

[@oosha2000]

The reason for having loopback in this game unlike the others is because the levels are longer so it's possible to glitch through the zones

[@MHzJr]

these video will be broken in a few months when annotations are removed...

[@heartistv]

@ORKAL There's another music error: In Sonic 3 alone, it plays the Major Boss music instead of the Minor Boss music.

[@alienspacebat5218]

"Tails is a traitor." I've got to make a fanfic of that.

[@inwencja2009]

However, the creator of twozerofoureight stops you. Creator of TwoZeroFourEight: "You cannot make fanfics!"

[@chasethehedgefox3740]

Like the "BETRAYAL" image of SMW?

[@alienspacebat5218]

Magdalena Bartosiewicz TwoZeroFourEight who?

[@inwencja2009]

2048 a game

[@alienspacebat5218]

Magdalena Bartosiewicz Ok, looked it up and it's totally irrelevant.

[@juiceala]

the one with Supersonic or Hyper sonic when you pass the boss area without fighting him , it happened to me a lot as a kid , it's one of the most annoying one ...

[@Sulphoraes]

one glitch that once happened with robotnik is that the rotors and the bombs loaded the wrong tiles and it was wierd

[@RandomAvatarFan]

I used to call this level "Glitch City" Sonic and Knuckles fixed most of it, but I still get the occasional stuck in a wall.

[@AgelessObsession]

I'm guessing it saves space to load both acts at once, considering they're both using the same palette.

[@anomalocarlos]

I was wondering about the water palette in Hydrocity myself, since I noticed that a) the water in the initial room of Hydrocity Act 1 only changes the background palette and doesn't change the color of foreground objects the way other water does and b) it is, I'm pretty sure, the only time in the Genesis Sonic games where you're in an area and the "underwater" area is not just everything below a horizontal line but visibly ends somewhere. Or where there's a water surface below other water.

[@RagnellAvalon]

rewatching these after all this time and wow I never noticed this. Despite it being plainly obvious.

[@yosifmukhled1720]

"You Don't Really Need To Become Super/Hyper To Do This Glitch" DID YOU JUST FREAKIN HOMING ATTACK???

[@hunlepto2239]

It's basically Classic Sonic's homing attack anyway.

[@anomalocarlos]

After seeing what happens when you loop back to the beginning of Act 1, I think the water at the beginning of the level isn't even the same object, in a programming sense, as the water elsewhere. It gets mangled in a way that the other water doesn't.

[@warueegeee1476]

0:37 Sonic: I have seen some shit.

[@hunlepto2239]

He has seen his fanbase.

[@Davidevgen]

i knew about the mini boss music glitch but none of the other. wow you sure have alot of time on your hands lol

[@KazzyMac]

Just so you know (unless it's already been said) At 3:10 where you say the loopback has been shifted up? It hasn't. Playing with Debug reveals that the water level is moved down a little when you reach the location of the boss. Regardless, I'm enjoying these very comprehensive videos of glitches ... so many things I've never seen. Well played. :)

[@bernarda1247]

3:10

[@dollors1]

Holy shit that knuckles glitch with the shark torpedoes is incredible!

[@erickhoch3359]

I think the main reason Sonic 3 and Knuckles is so glitchy is because the stages flow into one another, that means the game has a ton more to keep in it's memory and keep track of. more vulnerability, more fun.

[@PeaLover]

I love how you also edited some of the descriptions to not contain any swears anymore.

[@ThundagaT2]

Theres a slight variation of that last glitch, where you can walk past the Robotnik boss area, but the capsule isnt there. If you walk back towards where Robonik is, he should spawn as normal. I dont remember if it was Sonic 3 or S3&K that does that.

[@oosha2000]

Late reply but sonic 3 had that glitch, s3k fixed it

[@allennguyen4279]

u get all emeralds then beat the game after that u will be transported to mushroom hill zone act 1 get all super emeralds then perform a doble jump with 50 rings

[@oosha2000]

I remember doing boss music glitch by accident

[@oosha2000]

I also remember bypassing eggman in sonic 3, I couldn't move on so I had to reset the game. Fortunately, marble garden zone was registered so I could play on.

[@CataclysmToo]

Apparently, hyper sonic can act as an immovable wall for the 'unstoppable' force that is the wall of death.

[@SuprRooster]

I accidentally did the last glitch, but I was in the water w/ Super Sonic, so he died.

[@xippacheyne]

The 'Beyond the crushing wall' glitch can happen in sonic 3 too! And there is a glitch in Balloon park 2player (but doing sonic is almost impossible). Well, you hit the second balloon then cling to it (I am not mentioning about knuckles knuckles climb thingy, but when you hit the slope corner, don't stop holding left or it wont work and you fly up, then gravity changes and then, wallah! You're at the top of the map!

[@sunstarrock6336]

Missed the slope + Spring noclip glitch.

[@shalpp]

:40 That happens in Death Egg Zone with the little gravity balls

[@peterete1973]

0:40

[@randomaccount8009]

*Edit* This bug was already noted in ORKAL's first video from this series. If you still wanted to know what bug this was, click "Read more". If you fly onto one of the fans while it's on, Sonic won't move and will stay in the hanging pose until Tails stops being blown by the fan.

[@unuFPS]

These glitches are so cool :D thanks for the awesome vid

[@shootingstar7101]

9:17 So, what do we call this? False Super Sonic?

[@waddledee8108]

Edgeless super sonic

[@H057IL3]

Haven't played the game in a while, but wasn't the level called 'Hydropolis'?

[@CZGamer0]

Here's a glitch that kills tails: Get a bubble shield in act 1 and get to the boss. Beat the boss and let the goal post fall.Then keep bouncing until tails drowns. Stop bouncing after tails drowns and the stage will end and act 2 will start but tails won't come back. Once you get to Marble Garden he will be back.

[@SonicRainbow]

I did the loopback of Act 2 on accident a few days a go. Now I know what it was!

[@sonicfan2234]

OMG you are the god of all sonic glitchs :D

[@Xalusc]

That glitch about the song... Isn't the song already wrong? I mean, it starts playing Sonic 3 & Knuckles' miniboss song, instead of Sonic 3's... Then it changes to the boss song.

[@1DInciner]

Awww, thank you for this)

[@DigiTan000]

♫ Sonic and Knuckles are new. ♫ You can never tell what they're gonna do ♫ Sonic and Knuckles are new. ♫ You can never tell what they're gonna do...

[@zigaudrey]

Me too,but differaly,i go pretty fast without stop and a press the switch and we can't continue,unfortuannly.(Bad english,it's normal,i am french!)

[@Beagleman1996]

Does anybody know why S3&K's levels have loopback in the first place ?

[@l-i-a-m9232]

To fit the size of the level even if it's like 2 secs long.

[@dartichigungd1750]

the "HYDROCITY ZONE SEWER" its not hard on act 2

[@diamonddamory]

Finally I found someone that thinks it’s a sewer

[@oosha2000]

It's funny when super sonic gets sucked then he looks like normal gold sonic and word sonic glowing yellow

[@M3KAI5ER44]

Huh?

[@oosha2000]

It's difficult to explain it better but I found it hilarious. It kinda reminds me of both sonic 1 and 2 games. Using debug mode, I quickly turned Sonic to debug just before he turned to super Sonic and he looked like normal with his super state intact. Another one was having Sonic with his quills upward after reaching the signpost using debug mode.

[@Kirbymon8]

Knux is purple underwater :P

[@danieliustaskevicius7622]

I can't control Sonic and Tails at the same time

[@gustavofeitosamaciel1408]

Danielius Taskevicius Two Controls.

[@SaturnRabbit94]

You must plug in the 2nd controller to control Tails.

[@ThisNameWasntTaken]

umm i am not too good at coding so maybe thats because i fail to see the logic in that but why do all these levels loop? why are the first stages still around when the second ones are loaded?

[@MrRafaelBCK]

You totally forgot the glitch where if you get killed by one of those piranha and drown almost immediately with just one life remaining you die twice and end up with 99 lives.

[@Gamesmarts194]

Wait, how do you get to Angel Island's loopback? Is it impossible, or is there just none?

[@4snekwolfire813]

Gamesmarts194 This is a glitch showing without use of debug mode. You need D.M. to reach A.I's loopback.

[@l-i-a-m9232]

There's one it's randum tho u dy at the intro using dm and cum back to life by using dm and hold right

[@strawberrykeiku]

Joseph Trahan h0i!

[@biancatherescuemouse3305]

No dying is needed

[@Lumpytoast]

Oh man, I remember the Sonic 3 Super Sonic error.

[@Stairmaster9068]

can you fight the boss when you end up submerging the zone? will the boss even load if you backtrack?

[@DXAshram]

This is Ashram from Sonic Retro. Nice stuff. Tails is only a traitor because you let him die so much. D=

[@ILovePeanutButer7181]

what is the music that starts at 9:30?!

[@oosha2000]

S3&k back to the past anybody noticed those glitches

[@dededethesuperstarwarrior]

5:52 Sonic: Dude let me out of there knuckles isn't here still! Knuckles: I'm here! I finished my coffee! Sonic: .... Knuckles: I'm late right? Also, what is tails doing here?

[@tehsonicfan4366]

In the sewers, the 128x128 chunks ID is 02. At some points of these areas there are 128x128 blocks are unused because the have glitchy mess. Going down out of bounds will cause level wrap and die. This happens because the address that is supported in debug mode to see the camera position, resets from Y position FFFF to 0000 which is the last number of HEX code. WHY THE HECK YOU CALL TAILS A DICK IN 6:03

[@conlia]

I got the Hydrocity Sewer Act 1 and Act 2.The Act 2 one was with Knuckles.😊

[@RandomAvatarFan]

Oh and btw, to get into Knuckles Act 2 w/ Sonic and Tails... where do you start?

[@Smasher869]

If you do the Spindash glitch and land on the ground sonic will instantley Spindash.

[@Armystuntman]

What's a loopback?

[@jummysgamecorner]

A copy of the main level that has no objects (rings, enemies, moving platforms, etc.) and is shifted up some.

[@waddledee8108]

So empty slots in S2 are EHZ loopbacks?

[@tom4465]

Really fun to watch 5/5.

[@supersonic7628]

awesome glitches

[@ikagura]

What causes the miniboss theme glitch?

[@jonathanthomas9259]

ikagura drowning music while fighting a miniboss.

[@jonathanthomas9259]

And not only that, it was left in the rest of the prototype before a certain king of pop changed it to his theme in the final game.

[@ikagura]

@@jonathanthomas9259 I know about those 2 things, I'm just asking why Sega put the boss theme instead of the miniboss one in Sonic 3 (the one with the Jacksonesque theme). It was probably an oversight in the game's code

[@Mr_Spade]

Each music track has it's own ID assigned (Viewable in the sound test) and when you are drowning it changes the currently playing sound to the drowning music, then when you get air again the game checks what level you're in to restore the correct music. The issue is when the game sees that you're in a boss fight it'll just default to a pre-set music ID when you get air again rather than actually checking if it's playing the correct music. Hope this terrible explanation sheds some light on it

[@ikagura]

@@Mr_Spade I think I got it... in Sonic 3 they may have mistakenly put the boss theme for the miniboss (but somehow fixed it in S3&K). But then why isn't the boss theme glitch fixed even in S3&K?

[@erickhoch3359]

I've heard both Hydro-city and hy-dro-ci-ty.

[@RobloxOfKirby]

We all recomend debug mode right?

[@mrtuffinmuffin5784]

@charizardmaster23 just start using the second controller :D

[@RacingStripeAV]

Out of curiosity, what purpose do the loopbacks and "sewers" actually have?

[@jbbajangamer]

the one at the start i dont get

[@RonaKurona]

Hidrocity sewer is Nightmare Fuel.

[@chevlin3386]

5:52 Where knuckles at?? Lol

[@RarefoilB]

Hey, maybe you can answer something for me: In the Super Gaming Brothers LP of Knuckles's story in S3&K, in Hydrocity Zone Act 2, when running away from the incoming wall, Knuckles just randomly died. Here's the link (it's right after 5:00): /watch?v=QOXAVGllEyw Can you tell me why? Or is it just because they were playing Sonic 3 Complete?

[@NataliaNeeSama]

If you do this with 06 you will pretty much spend 40 years of your life showing all the glitches XD

[@abc2390986]

4:30 that happened on me for few times

[@Stratratrob]

Sonic is scared of water so he probably was scared of the water

[@X3MCTZN]

Sonic goes super sayian.

[@Zoppyification]

i know this video is old but... How did you control tails?

[@kennysuavo]

i was able to do the tails traitor one. i held right as tails and fell trough

[@superjoker6]

i had this game and was my favorite. has many glitches

[@dj12699]

6:00 Tails: Sonic i'm tired of carrying you around, missing out of final bosses and having to die for you. You didn't care when I was shot down in Wing Foretress did you? Well now it's my turn! Sonic: No Tails, you wouldn't! *Knuckles arrives* Sonic: NO... *Switch pressed* Sonic: FUUUU-

[@gspice52]

I had a glitch I went threw a wall in water and that was on the Wii version

[@boringperson2989]

5:55 tails abuse the prologue

[@onthedre]

the ramp of death happend to me when i was playing as hyper sonic (level select) and then i died saying ... WTF!

[@ScoutGuy]

9:40 that happened to me multiple times for some reason, lol.
