11:48 that's the CPU trying to execute a reserved instruction that is supposed to make the CPU jump to a specific location, which this prototype has defined to a routine that displays this error it's typically used for system calls on 68k based computers, and is generally unused in Mega Drive games

[@Dboi_P]

Yeah, its big brain time

[@TetraBitGaming]

Good to know!

[@insertcoolnamehere937]

Interesting

[@ButcherGrindslam]

And that's the same error from Labyrinth zone.

[@InsaneEnergy]

In layman's terms, it's an error handler. Sonic 1 and 2 have the same error messages, though I've only ever seen them triggered in Sonic 2 via corruption, cartridge tilting or loading an incorrect save state.

[@PercyPanleo]

5:36 That sometimes happens when the game doesn't switch between collision layers properly, which can also break loops and overlapping platforms. As for Hilltop working in the 2P Versus mode, I kind of suspect that Emerald Hill and Hill Top use some of the same assets, just with different palettes.

[@emilycarrick3570]

I believe in early development (When the time travel aspect of the story was still intact that is) Hill Top was intended to be a past version of Emerald Hill. Hence why both zones *do* share some assets in common, palette swaps to make this less noticeable aside.

2 player existed since Nick Arcade, you just had to hold B in the level select menu while selecting a level I believe

[@nmuniz2]

he prob ment on the menu. like not a "secret"

[@rogertheenderman2683]

I remember when I was playing the Simon wai prototype and I think that I made the combination C+start , and It started the 2 player mode

[@cometkuma]

The weird spindash sound is actually a side effect of bad emulation or improper sound settings in the emulator. The ring sound however is all on the prototype. It's due to the pitch not reverting in the sound banks

[@Cinko420]

7:20 Wait, Wing Fortress was originally Sky Fortress? That explains why Sky Fortress in Sonic 4 is essentially Wing Fortress...

[@User-yt8js]

@@imdone8243 hey, part 2 was good.

[@twelve1844]

5:33 It might be a cause of Sonic's placement on layers of the stage, similar that you see in loops (Looks like a vertical array of rings. You would see it once you turn Debug mode on.). Super Sonic seems to bug it out. It's just my speculation, so I really dont know if its really true.

[@bigiballypico616]

2:15 that happend to me in the 2013 remake

[@yeetyeet3279]

I am Proto. Your security is my motto. *Sonic 2 prototypes leaked again*

[@RyanNeoHedgehogOfficial]

That's a terrible joke.

[@Shadownnico]

About Hill Top and 2P Mode: 2P Mode, due to using a different resolution than the rest of the game, uses a different graphic format, which is why most stages that weren't planned to appear in 2P mode look broken. Hill Top is an exception because it reuses its graphics from Emerald Hill, just colored blue, so most graphics are already in the 2P-compatible format. This is also why most things that look broken in either stage are things not meant for 2P mode (like Hill Top's exclusive assets or Eggman)

[@Shadownnico]

@@pixeltheumbreon7856 I doubt it, seeing as the main game, even back when 2P Mode was added, was already a Co-Op mode with bosses

[@campbellsonic]

Hill Top actually has some unused code pertaining to 2-player mode, including background parallax and removal of the rising lava sections, so it seems it actually was intended for 2-player mode and not just because it reuses Emerald Hill assets.

[@MonochromeWench]

also the background in hilltop zone gets corrupted in 2p mode due to insufficient vram for player 2's scroll and sprite planes so some background tiles get overwritten

[@DanknDerpyGamer]

Interestingly, the 2P for Casino Night gets buggy in the 1992-08-21 prototype in ways that don't seem present in the Wai prototype... maybe from the implementation of the rotating tile blocks? IDK, but it gets really funky sometimes with regards to the data in the high/low planes, especially on the Tails part.

[@irvincastillo1727]

I think the reason why the rings change sound is because the spindash gradually increases in pitch the more you press a/b, and maybe instead of only the spindash being affected, the ptich gets oocked and changes the rings' pitch too

[@spicybreadproductions1972]

Shall I explain why Hill Top works in 2P one year later? To put it simply, Hill Top is Emerald Hill with gimmicks slapped onto it and some unique tiles. They use the same primary tiles, blocks and chunks, meaning that if Emerald Hill was built to be compatible with 2P AND Hill Top from the very start, then of course a large majority of Hill Top would function too! Also note how the level chosen don't have animated tiles in their backgrounds, and that Hill Top doesn't load there animated tiles. They would need an extra set of animated tiles due to how animated tiles are created. Hill Top working isn't proof of it being planned, it's proof that Emerald Hill is sharing it's tiles like a good sport (Cough Cough Green Hill and Marble have the same grass and could easily share data, Cough)

[@77sugarcoated]

The early spin dash sound at 2:05 is actually a bit cool.

[@maribellira6997]

I have a Sega Genesis and the pre-installed Sonic games. Sonic 2 has the same sound when I have Sonic spindash

[@user-fy7un8tk3i]

2:05 I feel like I’ve heard that sound in Sonic Mega Collection Plus

[@GameBoothUK]

Pretty much all versions of 2 seem to do this on the Sega collections that went HD.. I think it's something to do with how it's being emulated. Definitely does it on every version I've played on PS3/4 and Xbox 360/XBone

[@retrohero64]

@GSG Brazil My dog can play Minecraft with me now! Though he keeps chewing on his X Bone

[@GameBoothUK]

I'm almost 100% sure that the messed up spin attack noise around 2:05 is present if you keep revving it up in any of the emulations of Sonic 2 in the Mega and Classic collections.. I think the mobile version does it if you keep it going too..

[@pastabowl7]

I have played the mobile one, and there is no sound error like that. Intead, it just doesnt get higher pitched

[@vertz1515]

The invincibility music is different is the August 21 prototype

[@classicgamer8713]

The noise made at 2:20 with the spin dash... I swear I remember hearing that when I spammed the spin dash attack, maybe it was another sonic game... but I swear I remember hearing a distorted sound when I mashed the button

[@user-fy7un8tk3i]

Classic Gamer I feel like it was in Mega Collection Plus

[@BetterDonutGamer]

2:05*

[@charlotteholmes3904]

I might happen to know a friend that knows one of the devs freinds that knows of the layouts, enemy placements, etc. Of sonic 2s scraped levels. Also he had a very odd cartridge to show us and told us it was between Simon wai and Nick arcade. Didn't see how clear it was... Genocide city was re- palated, but no floor, wood zone was called forest top zone, and was BEATABLE at the cost of your eyes. It originaly would have you face of against *or accurately against because there wasnt one so we made up a believable boss and put it in the code.* an eggman with a buzzsaw eggmobile. And hidden palace actually had scraped entry in the files.

[@notmorg]

You should Record a video about Sonic 2 Delta! All the zones are restored, casino Night has its own ols palette, Oil ocean uses Casino night 2 player music, and so fourth.

[@bangerbangerbro]

10:13 it's just a crack intro isn't it? Nothing complicated.

[@--medditrainianlinersrblx-15]

It's mainly like when CENSOR prototype when it was Leaked Simalr I did play the CENSOR prototype I only got to Metropolis Zone act 2

[@MDTravisYT]

Some things I want to point out: The spindash sound is just your emulator, it's pretty much the same from what I see Hill Top working in 2P is just because it uses the same chunks and graphics as Emerald Hill HPZ and WZ most likely haven't been worked on since HPZ hasn't been touched since the Nick Arcade proto, and Wood Zone not being touched since the Simon Wai proto, both of which I'm assuming were scrapped pretty early on

[@classicsonicfan64]

You forgot to say that Dust Hill wasn't a early name for Mystic Cave. It was mistakenly called Dust Hill. Dust Hill is scrapped level in Sonic 2 there an photo of Dust Hill zone

[@MDTravisYT]

@@classicsonicfan64 Actaully that's called "Sand Shower Zone".

[@turbo7993]

HPZ Has been worked worked on since that prototype. in the simon wai proto, it got the mystic cave 2P music. in the august proto, im pretty sure it got like 2 changes, and in the september proto, (IIRC), the tube finally forced you to spin.

[@0ctazooka]

2:04 That always happens in Sonic 2 and Sonic & Knuckles for the AtGames SEGA Genesis Emulator(I think). Another thing on the AtGames Genesis is that every sound(Music, rings, jumping spindash)is a lower pitch than the original release. Kinda weirdly similar.

[@MoneyHoneyBunny]

I actually like the idea of no boss music and keeping the normal map music.

[@YoshiKing8211]

Wood hill zone looks so cool, I wish they brought that one back in the mobile sonic 2.

[@mr.jitterspam9552]

Maybe hidden in a secret like with hidden palace

[@andyukmonkey]

Hill Top Zone wouldn't be a good fit for 2 player because of the section with the rising lava. The player in second place might just get stuck. Unless they removed the lava entirely.

He said "unless you call this playable cause I don't!!" With such excitement

[@kirbygamer0640]

Ah, so Tails in the first prototype acts like he does in special stages? Lovely!

[@xity-xfilms5228]

I feel like they should've kept the bouncing back animation when you bounce off walls when you spindash you mentioned in the other videos. They could've used it when Sonic got hit instead of just one frame.

[@elleshugon6807]

Hey! I just haved seen your video and I think I have something important to say. The "strange" early spindash and rings sounds in the Simon Vai prototype are re-used in the Atgames' Sega Genesis Ultimate Portable Game Player Sonic 2, Sonic & Knuckles and Sonic Spinball versions.

[@Sonicgott]

Thank you for covering these releases of Sonic 2 Proto types. I did a video on these a little while ago on my channel.

[@DryPaperHammerBro]

Those "weird sounds" are due to your emulator playing audio at 22100Hz.

[@TetraBitGaming]

I'm referring to the loud sound after the spin out, it appears to only be present in that build

[@DryPaperHammerBro]

@@TetraBitGaming Ah, not the revving of Sonic's engine?

[@GameAW1]

Also you forgot to mention: When you hack into the Hidden Palace Zone in the September 14 build, does it still play the Mystic Cave 2P music of the prototype or does it play the new song from the final?

[@IceHedge]

My expectations for the next prototype drop: " The Hidden Palace zone is playable, but first we need to talk about parallel zones."

[@GabePuratekuta]

I'm hoping for the pre-Sonic CD version with Wood Zone still being the future of Casino Night

[@zetaman8924]

@Gabe Puratekuta There is no build of the game with time travel, that idea was scrapped before they started production.

[@GabePuratekuta]

@@zetaman8924 Ah, okay. Some of the levels were worked on, though

[@campbellsonic]

Superman Mario The internal level order matches the time travel concepts, so it seems the time travel idea was still being used when development started but was quickly scrapped afterwards.

[@zetaman8924]

@campbellsonic that’s true, although I think it’s possible they already scrapped it, but used the level order they already had to begin with and switched it around throughout development.

I think the Simon Wai prototype should have been a thing, The sprites are like in Sonic Mania.

[@lPsychoMax]

That sonic spingdash weird sound is also in the sonic 3 pc version for some reason. If you spin dash really really fast the audio glitches out in the same way.

[@darkoyt9094]

5:32 for some reason the game counts this as a wall chunk instead of a bg one anf i the second shot he's inside the chunk, the checkered parts have collision.

[@luigibudd]

I think in an AtGames genesis emulator, the spindash noise you described in the first prototype is also present in there. Not sure about the ring noise though.

[@MonochromeWench]

Hill top mostly works in 2 player because it shares art with emerald hill just palette swapped. 2 player stages need level art that works with 16 pixel high tiles that interlaced mode uses. hill top however also needs too much vram for layout and the background tiles get overwritten with layout data in 2 player mode so corruption is seen in the background.

[@thehenyojourney7638]

For the next sonic anniversary, sega should add the unused zones

[@elijahthekid_]

@@TetraBitGaming Nice, I love hearing other people's opinions!

[@mariosonic76]

I’m not sure if someone mentioned this already, but whatever. Mystic cave zone was always going to be called mystic cave, the reason that it’s called dust hill is probably that because they mixed up the two stage names and they didn’t fix it yet by the time of the first build you talked about.

[@BaconCatVR]

My favorite level is hidden palace (not the one seen in the final release) mainly cuz music is a bop 🤘😎🤘

[@SheepsWithFangs]

Something I saw that might be important is the different spindash and ring sounds sound identical to this portable genius I have

[@zeketrujillo142]

I feel as though these prototypes more or less confirm that is all the work that was done for the three missing zones (though really two because from what I've read ideas and concepts for Genocide City Zone were used in game for Metropolis Zone act 3) and I think it is very unlikely they would have done something else to these zones, and then scrub some of the content out but then take this long to officially remove them.
