The emerald hill zone with almost no collision + glitched background is actually the only remains of labrynth zone in the final game.
Also, the very wacky one is actually wood zone, and the reason it reloads chunks is because knuckles is both moving & not at the same time. So the game adds the chunks so it looks like he’s moving through the map.

[@Brainulator9]

I thought what happened was that the scrolling code for Wood Zone was removed.

[@TheRZone.]

@@Brainulator9 You are right, it was removed in REV02.

Ah yes, my favorite sonic character that doesn't chuckle, Tails

[@Varkyorsomethingstupid9963]

I don’t remember tails not chuckling (I get the joke btw)

[@Devinifys]

This is honestly the coolest thing to see how breakable Sonic 2 can be with debugs and glitches

[@coinhats]

Wood Zone and Hidden Palace remains are easy to tell, but the others are not. The one with Emerald Hill's music I think is ether Ocean Wind or Tropical Sun. The one with Oil Oceans music was the slot for sand shower and the one with the Sky Chase music was ment to be ether Winter Zone or Rock World.

[@HyperStormH]

The “Winter Zone” IS Rock World Zone. That was the name of the winter zone.

[@coinhats]

@@HyperStormH thanks for the info. :)

[@GimmeMoreStorage2763]

The one with Emerald Hill’s music is actually remains from Labyrinth Zone in the nick arcade proto/sonic 1.

[@Vodka5.56]

Those two unnamed slots were the leftovers of Genocide City and Dust Hill zone

[@ritaandrunt5767]

This is absolutely amazing I'm always fascinated by unused sonic zones that never made it into the final version also how where
You Able to access these zones in the final version of the game ?

[@TiyanaWhiteLake_2nd]

Knuckles in Sonic 2 = Sonic & Knuckles + Sonic 2 (Final Ver.)
Right now I don't understand something, do you think that this is not the final version?

[@ritaandrunt5767]

@@TiyanaWhiteLake_2nd I just wanted to know how you were able to access these unused level's in the final version of this game

I gotta give you credit for using the PAL region for the MD emulation.

Looks like a glitched damage sprite

Eu fico impressionado de ver como que os gringo consegue quebrar o jogo tão facilmente desse jeito 🤔🤔

[@Gameboy_1992]

So where is hidden palace zone? The music and glitched graphics for it still exist, aswell as the unused stage its self, but in a way to glitched state

[@_eesports]

The glitched graphics are just the corrupted sprites. I think the collision still exists, though.

[@SonicEclipse456]

They must've deleted the sprite data for the zone which is probably why the zone looks like a garbled mess. For some reason they still kept the collision data for it though

[@thebluescratchy2009]

@@_eesports when level imported, its still glitchy so its unlikely that the collision is from hidden palace and its from a different zone.

[@toastedstuff]

The real problem with the art that the game wants HPZ art to be Kozinski compressed, but it is Nemesis compressed, so it shows up a glitched up mess due to incorrect compression issues.

[@dalebenton3354]

saw these extra Levels in sonic debug mode,Just having to find the right software to get them active for the game,I could easly replace every thing and get it so Sonic run on the hills,Not having to fall through any of them,Makes ya wonder why Sega removed some of the zones before the day it got released

[@thatlutherfan]

with some of the older prototypes of the original game you can access these zones. (edit. i kinda mean like some levels may actually load in prototypes. not buggy messes)

[@CaffeinatedCoffii]

Thank You captain obvious

Lives counter: says Miles
Character: is Knuckles
Me: That makes total sense!

[@Luke-vg7rj]

The part about this is that knuckles is not supposed to be in sonic 2

[@dmansworld]

Is no one talking about how the music was from emerald Hill to oil ocean to sky chase zone

[@dmansworld]

To metropolis zone

[@GigantoGaming801]

​@@dmansworldIt's because those unused level slot are for respectively Ocean Wind Zone, Sand Shower Zone, Rock World Zone and Wood Zone

[@GigantoGaming801]

​​@@dmansworldOcean Wind was originally going to share emerald hill with obviously emerald hill, the oil ocean final game music was originally planned to be for sand shower, sky chase music was for Rock World, and metropolis would share it's music with wood zone (and no wood zone's music is not emerald hill 2p, emerald hill 2p music was for Blue Lake or Tropical Plant Zone)

[@StevoVolGreeno]

A shame they couldn’t have added the extra stage data in the Knuckles cartridge for sonic 2…. There was room.

[@Wmx2011]

*miles*

the code is not working

[@TiyanaWhiteLake_2nd]

What kind of emulator do you have that the code doesn't work?
Double-check how you entered it
