The Sonic & Tails Demonstration Sample ( ソニック＆テイルス 実演用 サンプル), is a sample version of Sonic & Tails, known internationally as Sonic Chaos, for the Sega Game Gear. It was released by SMS Power on December 12th, 2010. It was likely used in game stores to demonstrate the Game Gear.
- The only Levels available are Turquoise Hill Zone and Gigapolis Zone. Level select can only access these two levels.
- Internally the demo build is referred to as version 0.99 and dated 1993/09/14. The final version is referred to as version 1.01 and dated 1993/09/07 which is a week earlier than the demo build.
- When completing the game the text "COMMING SOON" appears along with a voice sample also saying this.
- Not a difference, but all demos cutscenes are intact and previews the same levels. Mecha Green Hill Zone can be seen even though it is not playable.
