Extra Special Stage

File:Scdextra.gif

An extra special stage can be accessed from the Sound Test menu by setting all the 3 selections to 07. According to a former Sega Europe QA Tester, an extra Time Stone was to be collectable here. When collected in addition to the previous Time Stones, "S" TV monitors would appear where the ring TVs were previously located. When broken, you would morph into a gimped version of Super Sonic, which would simply grant you invincibility and greater speed. Graphics would not change.

Unused Music Loops

Within the ISO for one of the Sonic CD prototypes were some specific files, preceded with the letters "SNCBNK", with a number afterwards. The numbers referred to the timezone for which the file represented.

Each file is a small music loop, played using the PCM chip on the Sega CD, in accordance to the timezone it represents. Speculation has been rampant as to their use, but two theories have stemmed that seem to be relatively plausible:

  • They were intended to be used to bridge the gap between when a CD audio track plays and when it starts again. (Shadow Hog)
  • They were intended to be played at the start of a level, before the CD audio played. (StephenUK)

Of course, there's no concrete evidence to support either idea, but it's an interesting debate nonetheless.

Get the files here, courtesy of ICEknight. Get Shadow Hog's edited files merged with the CD audio tracks here. Check out discussion of this oddity in
Sonic Retro
this forum topic.

Prototype Music Tracks

In the 510 beta of Sonic CD, there were two distinctly different music tracks not featured in the final version of the game. scd510_28.mp3 is an alternate speed shoes track, while scd510_25 is an alternate title screen track.

Get them here.
