A sample version of Sonic Chaos, likely used to promote the Game Gear.

Differences#

• Only Turquoise Hill and Gigapolis are playable normally, though Mecha Green Hill and Aqua Planet can be seen in level demos. It is possible to change address D299 to access otherwise inaccessible zones. The values go from 00 to 05 for regular zones, and from 08 to 0C for Special Stages.
• The level select is the same, but it locks onto Gigapolis once you are at Gigapolis Zone Act 3.
• Tails’ ending sequence is unfinished, with no proper way to finish the game as him.
• The demo is internally referred to as "Version 0.99", while the final is labeled "Version 1.01". It's also dated a week later than the final.
• Once the game is completed, or a demo finishes, a black screen with "COMMING SOON" will display with a voice sample before the game resets.
