Ending Details
Chaos Emeralds & Super Forms: Collecting all Chaos Emeralds allows players to access the "S" Monitor, which instantly transforms Sonic, Tails, or Knuckles into their Super forms.
Regional Differences: The hack makes the original Japanese credits and sound test endings accessible on all versions (USA, European, and Japanese).
Boss Battles: The final segments in Hard Mode feature enhanced boss AI, specifically for the GHZ (Green Hill Zone) and SYZ (Star Light Zone) bosses, making the path to the ending significantly more difficult.
True Ending: Achieving the "best" ending typically requires collecting all six Chaos Emeralds. In many showcase versions, this leads to a celebratory screen showing the character you played as (Sonic, Tails, or Knuckles) with the message "Sonic Has Passed" or a standard victory screen.
Relation to IDW Comic
Many fans confuse the rom hack's plot with the Sonic the Hedgehog 30th Anniversary Special comic (Seasons of Chaos), which was released around the same time.
Comic Ending: Sonic and his friends (including Mighty and Ray) defeat the Heavy King, who had betrayed Dr. Eggman.
Final Scene: The heroes split up the Chaos Emeralds to hide them, and Sonic runs off into the sunrise, acknowledging his friends' help.
