Talk:Sonic Adventure (Dreamcast)

I know that there is an unused pacifier for the Chao Garden in SADX. I got it using the PC version's memory editor. Somebody should look into it more and see if it's also present in the DC version. Basically, when your chao places it on its head, like a pumpkin, it'll make his head turn invisible. On the ground, it looks like a pacifier. {EspyoT} 11:47, 5 June 2011 (EDT)

Another thing. I was reading TVTropes, and read about the oversight in which you can get the Crystal Ring in the Last Story. If you do that, the game will give you a summary of the story when you choose to start Last Story (that shouldn't happen). But the thing is, the troper who wrote that mentioned that the background image for that summary consists of an early concept art for Perfect Chaos. I'm assuming this isn't used anywhere. {EspyoT} 09:52, 15 February 2012 (EST)
 * Trying to speedrun the game right now (stupid Big stages, ugghhhh...) but I find it difficult to believe this, if only because if Chaos can be seen, isn't the image... used...? WhoIAm 22:00, 3 April 2013 (EDT)
 * Are you referring to the early concept art mentioned? If so, it wouldn't be seen in normal gameplay, therefore considered "unused". --AquaBat 22:37, 3 April 2013 (EDT)
 * There's nothing unused about it. If you manage to trigger an autosave (by completing an Action Stage or obtaining the Crystal Ring) on your first playthrough of Super Sonic's story and exit Adventure Mode, a recap will show when you return, with an image of Perfect Chaos in the background (SMRYBG_SUPERSONIC.PVM) and playing Chaos 0/2/4's boss theme. It is rarely used, but not unused. MainMemory 22:40, 3 April 2013 (EDT)
 * Oh, so the image appears when you complete a stage on your first time through Last Story? Hmm... Still, I bet only around 1 out of 30 players ever did that. Should it be noteworthy nevertheless? I mean, the grand majority of people don't even know the Last Story has a "on the last episode" screen. Wouldn't be the first article to point out something that's very rare. {EspyoT} 17:08, 4 April 2013 (EDT)

Unused song
An unused song in Sonic Adventure? Can someone confirm if it's real, and if it exists on the DX versions? {EspyoT} 09:53, 26 February 2012 (EST)


 * This isn't real. It is a song called "Flex Through The Solar System" by dRamatic & dbAudio. --needtobealive 11:26, 16 March 2013 (EDT)

The Spring in Emerald Coast
It's a well-known glitch to get Tails/Knuckles/Amy, etc. into Sonic's Emerald Coast. Thing is, all these characters start the second segment of the stage in a different place: next to a spring placed beneath the playable level. Here. Would that spring be considered "unused" as it is not normally visible under any circumstances? WhoIAm 22:00, 3 April 2013 (EDT)
 * Unless it has a different design than the other springs, no. It could be considered an "oddity" of sorts, though. --AquaBat 22:37, 3 April 2013 (EDT)
 * The part that interests me is that it seems to be a sort of generic "dump zone" for any character other than Sonic; the fact that they took the time to place it there could mean other characters, at one point, were allowed access to the stage. WhoIAm 23:00, 3 April 2013 (EDT)
 * The location is (0,0,0), which is the default position in any stage a character should not be in. They may have put a spring there to prevent Tails from falling into a bottomless pit either before his cutscene was implemented or in case it failed to load. MainMemory 23:07, 3 April 2013 (EDT)
 * I didn't know that; that's interesting. What is in this position in the other Action Stages? WhoIAm 23:10, 3 April 2013 (EDT)
 * Sometimes it's well outside the stage, other times it's in some random part of the stage, it all depends on how they built it. In Emerald Coast part 1, (0,0,0) is right at the start. MainMemory 23:15, 3 April 2013 (EDT)
 * I see. In any case, I'm placing the spring in the main article as an oddity; feel free to remove it if it doesn't belong there. WhoIAm 21:42, 6 April 2013 (EDT)

Sky Chase: Dragon and Sonic Jam models
I recall seeing videos of an unused mechanical dragon boss in Sky Chase. The Dreamcast version reportedly shows old Sonic Jam models of Sonic and Tails during the plane transforming sequence in Act 1. Can this be confirmed? WhoIAm 20:38, 8 April 2013 (EDT)
 * The dragon is presumably the original boss of Act 1, but it was removed. It can still be seen in debug functions, but it doesn't do anything except follow the player. The Sonic Jam models are only seen in pre-release screenshots and perhaps some obscure footage; contrary to popular belief, it's not in the final Dreamcast version (not even the first Japanese release). The models are, however, low-poly on the Tornado, and so they can still look like the Sonic Jam models from far away and may be modifications. LinkTheLefty 21:43, 8 April 2013 (EDT)
 * Okay. Somebody should rip the model of the dragon (it's in SADX as well). As for the old models... ah, I see, you're right. Just lower-poly ones complete with green eyes. Someone on Sonic Retro hacked the game to always use the alternate model. I swear, those smaller, shorter spikes and shorter height really do make him look classic, but the green eyes give it away. You can't tell on a 240p Youtube video! WhoIAm 21:46, 8 April 2013 (EDT)
 * No problem. The Sonic Jam models themselves might still be buried in the game disc somewhere, but if they aren't extracted at this point then I doubt they're still there. LinkTheLefty 21:58, 8 April 2013 (EDT)
 * RE: the dragon (AKA "BOSS"): Sonic Retro says hi, and not one, but two videos from the PC version.
 * And the post on the low-poly model hack:

Jam Spring
I just thought I'd mention that the alleged spring from Sonic Jam that's on this page isn't actually from Jam. It's similar, and without the Jam model, you wouldn't be able to tell. Luckily, I happen to have the Jam Model and I can reference the differences between the two. Heck, I might even be able to throw a picture or two on the page if it's fine with you.

As for the differences, here they are: The Jam spring's topper is about 3/4 the height of that unused model, the spring's bar coils the opposite direction, and the Jam spring does not have a base on it. It should also be noted that the texture used on the unused spring's topper is (as far as I can tell) not used anywhere in the game, but when the textures for the spring from Sonic Jam are applied, they fit the model perfectly. --BetamanOmega 16:34, 4 May 2013 (EDT)
 * The page doesn't say it's from Sonic Jam, just that it resembles the one from Sonic Jam. I'll make a note about the texture from Sonic Jam fitting it, though. --BMF54123 16:36, 4 May 2013 (EDT)

Whoops, wrong article. I meant to go edit the one on Retro because that one does say it's the same spring from Jam. My mistake, but please do post the information about the textures, especially the note about the potentially unused texture. (Currently being used as a texture for the topper on the spring itself.) --BetamanOmega 16:38, 4 May 2013 (EDT)

Big proto release
The folks over at Sonic Retro found the oldest known proto of the game- it has some nice stuff like test levels and the EARLY WINDY VALLEY. Here. WhoIAm 17:30, 22 May 2013 (EDT)
 * The link goes to a forum 404 – here's the proper one. (Also, holy crap this needs to be hacked into a legitimately-playable form.) -WarioBarker 15:19, 24 May 2013 (EDT)
 * Sorry about that, they moved the thread sometime after I posted. Well, they've made some headway into the playability of it (and a download link is provided), though my ineptitude with anything Dreamcast-related means I can't dig into it for TCRF. So far, they've found 2 test levels, two early Chao gardens (Egg Carrier's, seen in some magazine scans, and Mystic Ruins), early Windy Valley of course, and early At Dawn from Speed Highway. Apparently most other levels have differences as well. WhoIAm 02:59, 26 May 2013 (EDT)
 * There are actually three test levels, just the third one crashes my level editor and SADXPC. It apparently does work in the demo thought. MainMemory 09:28, 26 May 2013 (EDT)

Unused Levels videos
On Psychojason's channel (On YouTube) he posted videos of the Beta and some unused levels recently. Should we document the Beta videos in a Beta/Prototype page and the unused levels for the final release in here? --Gamefan759 12:27, 26 May 2013 (EDT)
 * I think we should just make a proto page and put everything there. WhoIAm 15:09, 26 May 2013 (EDT)

Censored Neon Cowgirl
Removed in all subsequent versions but I can't find a half-decent Dreamcast emulator to compare the two on. Is this notable enough to appear even?--PerfectDark 00:52, 14 July 2013 (EDT)


 * I believe the cowgirl was replaced by a generic Casinopolis board. There's actually a bunch of little differences that the original Sonic Adventure release in Japan had besides minor glitches, some of which can be read here. Considering the games beforehand had minimal changes outside the manuals and the games since mostly simply change the default language, this is probably the Sonic game most deserving of its own regional differences section. LinkTheLefty 01:38, 14 July 2013 (EDT)


 * The object was completely replaced in subsequent versions of the game. The cowgirl and billboard occupy the same slot in Casinopolis' object list. MainMemory 09:41, 14 July 2013 (EDT)

Well, I'd definetly include it if I had the means. Only the '98 Japanese version has it, not even the "International" re-release. Makes a noise when you bump into it too!--PerfectDark 16:44, 15 July 2013 (EDT)
