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

• 

  May have taught about Knuckles' special moves in multiplayer.

• 

  May have taught about Tails' special moves in multiplayer.

• 

  May have talked about the music melody powerup.

• 

  Used to possibly explain about how to pick up objects.

• 

  May have described how Sonics homing attack worked.

• 

  Possibly used to explain about powerups.

• 

  More possible explaination on powerups.

Lost DC Controller Tutorial Screens

• 

  These were likely used to explain how to move your character around. In the final game it's Omochao who teaches you how to use your controller.

• 

  The analogue stick.

• 

  The face buttons.

• 

  The D-pad and start buttons.

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.
