Sonic Month 2019: Sonic 2

Can we just take a moment to appreciate how incredible it is that these two builds have finally been tracked down and dumped? Seriously major kudos to drx et al for what they do.

 

I am very excited about these finds but sifting through the pages of the topic and scrolling past debates on what Dust Hill was is tedious and I don’t think it is anything to care about too much. All the evidence is available and can be interpreted in whatever way you like but it isn’t anything worth thinking much about let alone debating over on the internet. There are so many other cool things to talk about right now. But, that is only my opinion.

 

An interesting build for sure, all these builds really show how quickly the final game came together just months before launch.

 

Seconded the desire to not discuss Dust Hill Zone in this thread

 

Object $5a is some kind of badnik that's not referenced by any debug table:

It "spawns" in place and follows your movements. It doesn't do much else, but it can hurt to the touch. If you kill it, it leaves behind tiles. This might be the bubbler badnik?

It's mappings look at $7880 in VRAM...

The code for all the bosses sans the Wing Fortress/Death Egg ones are present. In the stream, drx was able to load ARZ and Metropolis. What people might not have noticed - the object itself is coded to spawn toward the end of the stage in Act 2, not Act 3 (!!!). However, the routines that set the camera/field and loads the boss up when you're within a certain coordinate sets it up for Act 3. Chemical Plant and Oil Ocean are present, but Chemical Plant crashes for some reason (it doesn't have hard coded coordinates, so it's likely meant to be placed in debug mode). Not sure what's up with Oil Ocean, could be similar to Metropolis.

I started disassembling the ArtLoadCue tables:

• Near the end of HPZ's PLC, theres a few entries for cut badniks for some weird reason. They all load at $8000 in VRAM though, so what's the point of these? AFAIK, this is NOT in Wai.

The Nemesis art for the Wing Fortress/Sky Chase badniks are present, but aren't referenced by any PLC entry in the tables. It doesn't look like Silver Sonic exists yet.

Casino Night's PLC entries contain the art for the other non badnik objects, even though the objects themselves are not present in the debug object list! They seem based on the design of this early Casino Night.

 

>oldbies having to give out history lessons

Oh boy.

 

The August prototype is the only one besides the Wai prototype where the splash tiles (not the waterline) in Aquatic Ruin are animated correctly. They broke sometime between this prototype and the September 14th build.


It's also the last known build to have the cut upper route in Mystic Dust Cave Hill Act 2, though most of the second half has been blocked off. These rings were added after the Wai prototype and are still in the same place in the final version.

 

Wonder if it had something to do with this.

 

I'm thinking it might be a (vulnerable) Crawl/Sandcrab, crawling out of the ground.

 

and of course Hidden Palace is using the 2-Player Mystic Cave music and the "$10 track" is present already as well in Sound Test.

 

In terms of public builds, I think we might be done with Sonic 2 (is there a proto with CNZ using the beta colors/tiles w/ objects though? ) - but (aside from that one, if it exists) I'd imagine that there is still a lot of the development cycle (mainly between the NA proto and Wai proto) that we don't know a lot about / we'd need to hunt for internal builds if we wanted to piece together more.

Plus, even if we didn't necessarily have more questions, it'd be cool to see how the game developed between the NA proto and Wai proto.

 

Most likely she just wanted to appease the interviewer. She sounds quite annoyed throughout it.

It's also worth noting that she consistently refers to it as simply the desert level in said interview.

Thanks to the new protos, it seems we can safely say that OOZ was originally going to use CNZ2P's music track. OOZ's final music track was likely intended for the scrapped desert zone (ID 03) early in development.

 

But … how would OOZ's music fit a desert level with saguaro cacti, and other hallmarks of a very much American-esque desert?

 

Ok so for this recent build, HPZ had the most functional demo... why?

Bizarre stage. One of the 1st in the game and one of the most presentable for like 60% of the game's development cycle. Then just scrapped. Dead.

The fuck HPZ

 

I still say that while we might have a quenched thirst for now with Sonic 2, I wouldn't say we should completely cease looking for more protos, and declare everything solved (which I can't help but feel like some might be doing in light of these monumental releases). If anything, just shift focus towards trying to find intenal builds IF POSSIBLE. Finding any (more?) would not only paint more of a picture about development between the proto released today, and the one released yesterday, but also paint more of a picture of the development between the NA proto and the Wai proto (as well as painting more of a picture of the development between the beginning of development, and the NA proto)

 

I am crazy, or...



(Tried to acess the Special Stage.)

 

I've got to say, I'm a little surprised to see that they implemented the final Sonic sprites this "early" in development. I mean, of course, it's not early at all, but this kind of polish strikes me as something that could have been part of the "September crunch", something hastily put together sometime during "Beta 1" or something. I kind of assumed those scans and footage showing HPZ or proto CPZ with the final sprites were closer to the final game than to Simon Wai's. Good to have that finally put to rest in any case.

 

The stage demos are still using the same input as they did in the Nick Arcade prototype; they only recorded new ones after Beta 8. The difference with Hidden Palace is that its layout never changed.

 

@NeoFusionBox The special stages are just a corrupted Sonic 1 special stage.

 

The music and graphics were designed by different people independently of each other. Both staff only being told "desert level."
