(GG) Sonic 2 Auto Demo Prototype (1991-12-05) - Info & Download

While we're on this, I've heard there are subtle differences between the Game Gear and Master System layouts, particularly in Green Hills Zone, to take into account the differing screen resolutions. We could use those too.

(actually this applies to most prototypes - it would be nice to make direct comparisons between, say, all our Chaotix prototypes).

 

I would dig up the quote but they mean the level designed area is there, the spot where the mock up was taken.

 

I'm not sure if this has been already said, but in Zone 03, Act 01, which is the UGZ level played in the auto demo, you can actually jump into the ceiling and keep jumping once you reach the top, run right, jump, and discover the rest of the level.

 

xD I'm actually working on a disassembly of the game myself too. :v: I'll probably stop working on mine though.

 

Working on it...

...give me time, the tile pixel format is horrendous.

 

Looking at a savestate, it looks like there is monitor art loaded. I wonder if there's any working monitors (or any other objects) in there?

 

That's looks like an earlier version of Green Hills Zone act 3.

 

Whee.

And no, I didn't figure out how to rip them automatically, 'cause I'm dumb.

EDIT: Green Hill 1.

EDIT 2: I continue to be a dumb. Green Hill 3.

 

You removed the first one you linked though :v:

 

Yeah I noticed the monitor in the tile viewer, but it seems to load in on the sega screen and the opening and the title screen which it does not in the final game. Pretty odd

 

The giant palmtrees are very nice, actually!

Thanks for the maps GoldS

 

And here's Green Hill Act 2. Lots of places to go above the screen and crash the game. Plus, some of those rings at the top aren't even visible on screen.

Note that long string of rings, which was broken up into two sections in the final version. Obviously the floating platforms haven't been coded yet. There are a lot of other changes too, though the basic layout seems to be in place already.

EDIT: Sky High 3. Not much to see, but here's the map anyway.

 

The content in this early prototype almost ruins the final product for me. This version of Green Hills Zone is so much better, and so many gimmicks/decorations were cut that it pisses me off in how empty and dull the final was. I already felt extremely iffy about how unfinished the final felt, this just seals it: I'm pissed at Aspect for their sloppy development and wasted potential.

 

there are similarities but it looks to me like they re-worked the levels from scratch. It's not as simple as replacing a tileset, anyway.

 

Definitely agree - each version has definitely been based on a similar structure, but the actual specifics of the layout have been redone completely. Some bits are longer, shorter, taller or just removed entirely from the final layout.

 

Oh wow, well it looks like someone beat me to it...

It's really interesting how the layouts look far more complete or arranged correctly than they do during gameplay. They come off as rather messy and all over the place, until you have the chance to see it entirely from a distance =%

 

This is the only kind of candy that keeps bringing me back to retro. Keep up the good work guys !

 

I feel the same way, it's a shame they had to cut back and simplify the detail in stages for what ever reason.
