A short playable demo made exclusively for Japan of Sonic Adventure for the Sega Dreamcast.


The Cutting Room Floor research
  • Made a few months after the initial Japanese release.
  • The build seems to be loosely based on the initial Japanese release as it still contains all the files used in the original with slight alterations.
  • This build seems to have been made around the time when work on the International versions had just started.
  • The build contains level layout and other aesthetic changes to make the game overall much easier than the final (for instance, Chaos 0 dies in one hit, stage hazards in Emerald Coast have been removed, etc).
  • As Sonic, the game ends after the conclusion of the first Eggman boss battle.
