Pressing Start allows the player to move Sonic and Tails' X and Y positions with the D-Pad, much like the Debug Modes of prior Sonic games.These functionalities were retained in Chaotix, though the jumping and holding buttons were separated and a recall button was added due to the controls being too complicated for one button. The A, B, C, X, Y, and Z buttons all share the same functionality, causing one player to jump, the CPU to stop moving, and, if close enough, one player to pick up the other (and throw him).

While it's similar to how it ended up in the final, there are some key differences: The primary game mechanic of Chaotix, the rubber band-like rings connecting the two playable characters, has been implemented at this point.While Fields were cut by the 1207 prototype, Chaotix kept the "Attractions" name for its levels. The game is split between four playable levels: "Attractions", side-scrolling levels similar to those seen in previous Sonic games, and "Fields", overhead levels that have no collision detection.Meanwhile, Tails was cut by the 1207 build, though his behavior was functional until the 0119 prototype. The player controls Sonic and Tails, both of whom were cut from the final game but not entirely scrapped - Sonic was retooled into Mighty the Armadillo by the 1207 prototype, as evidenced by the two's sprites being practically identical.However, the basic mechanics that serve as the basis of Chaotix are present at this point and similar to how they ended up in the final.
