Unused Artwork
Special Stage Art
These are various graphics that can be found inside the games disc.
Big the Cat
[1] In certain cutscenes, Big the Cat is viewable via pressing buttons at a certain time, he is also in many levels, although he was removed from the levels in Sonic Adventure 2: Battle he is still in the cutscenes. For example, in the Dreamcast version of the game, In the cutscene after fighting Knuckles/Rouge, press and again and again to make Big appear and walk around.
Trial Version screen
A screen displaying a Trial version warning can be accessed.
Early Sega Logo screen
Early Sega Logo screen.
Trial Title Screen
Leftover Trial Title screen.
2p VS Menu
Text for 2P VS menu system. Green Hill is listed meaning it was probably a 2P VS level at first.
Early Menu 1
Early menu system in English and Japanese. Note how Playground and Library are listed, but were not a part of the final game. The Black market was also unused in this game, but were used in the updated GameCube port. A Black market was actually available in the Dreamcast version but was only accessable on a website.
Early Menu 2
This Menu, which was found in demos, had only 3 options and each option lead to a single level each.
Early Menu 3
These graphics were used for another menu system. Rather than drawing out the text the text would have been placed on top of these.
Lost Tutorial Screens
Lost DC Controller Tutorial Screens
World Ranking System
There are a few remnants of a World Ranking system in the game disc. It was in Sonic Adventure but it was left out of this game. The following text could be found in Advertise.prs. advsng_3.adx refers to the regular menu music which would have been used here also.

After further digging in the disc more text is revealed which would display onscreen. There was a login and registration (probably to reduce cheating). The rankings could have been searched by country and name. It referred to the world ranking system as "The Sonic Network." The text was translated into numerous languages such as French, German, Japanese, Spanish.

The images below display remnants of the world ranking system also:
Trial Screen Ending
A screen which was used in the Trial version in its ending.
Black Market
The menu in the first picture indicates the presence of a Black Market. The second picture was actually from Sonic Adventure 2's website. The textures shown in the third picture were extracted from AL_STG_KINDER_BL_TEX.PRS on the game disc.
Playground
The first picture shown can be found in-game and provides solid proof of a Chao Playground existing at some point. The second picture actually shows some textures which were extracted from AL_STG_KINDER_PL_TEX.PRS on the game disc.
Library
These images show an unused Library for the Chao Kindergarten. The models are found in CHAOSTGKINDER.PRS and the textures in AL_STG_LI_TEX.PRS.
Unused Themes
The following images show various themes which can be found on the disc, but are not usable.
The nexus memory card save containing one theme can be downloaded below:
Level Maps
Tails Prison (Lane)
Start: rightmost outcropping of yellow block at right
End: magenta block at top left (the red block is the Laser Blaster room)
Hidden inside the disc is early maps of various levels. These maps don't go into very much detail and in a few cases disagrees with the level layout found in the final game.
Debug Menu
There is a debug menu in the game which is accessible by hacking. In the Dreamcast version, you can replace ADVERTISE.PRS with TITLE.PRS; in the GameCube version, you can replace advertiseD.rel with titleD.rel; in the PC version, you can use a memory editor to go to 434687 and change CC 76 8B 00 to 98 8F 8B 00. The code to display the menu items onscreen was removed in the PC version, but it still functions.
The menu has the following options to choose from:
- GAME:1P ONLY - Play a level with one player.
- GAME:2P 3POINTS MATCH - Play a level with two players until one player wins three times.
- GAME:2P 1POINT MATCH - Play a level with two players.
- TEST:EVENT - View cutscenes.
- DEMO:1P ONLY - Record a demo with one player. Press Start to end the recording.
- DEMO:2P - Record a demo with two players. Press Start to end the recording.
- DEMO:LOOK PREVIOUS TAKEN ONE - Replay the previously recorded demo.
- PLAY:FROM HERO - Play the story mode on the Hero story.
- PLAY:FROM DARK - Play the story mode on the Dark story.
- PLAY:FROM LAST - Play the story mode on the Last story.
The GAME and DEMO options will ask you to choose a character or character set and a level. The list of levels includes all that character's normal stages, the test level (listed as BASIC TEST), Chao World (misspelled as CHAO WARLD) and occasionally SONIC TEST or KNUCKLES TEST, which do not exist in any version of the game, and crash if you try to select them.
The Event Test not only lists all the events and allows you to view them, you can also stop cutscenes with the B button, and speed them up or slow them down with the shoulder buttons, even making them run in reverse. Video of cutscene viewer
