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.

6 Unused World 2 Field Level Palette CycleĬrackers is extremely incomplete and unpolished.

Much later, various Crackers graphics were used for Egg Gauntlet Zone in the 2013 version of Sonic 2, although the Zone was never normally accessible and both it and its assets were later removed. Also, 'JUL.1994' can be seen when viewing the ROM through a hex editor, which may not mean much given that among the unused graphics in a June 1994 prototype of Yuu Yuu Hakusho: Makyou Toitsusen are sprites for Tails that are not in this build. The later discovery of several Chaotix prototypes in 2008, especially the 1207 build, proved that this was not the case.

The '19940401' date led to much debate on whether the title screen (a peculiar ASCII-art design that looks like it was thrown together in 5 minutes) or the ROM as a whole was a joke of some sort. The available build, dated Apon the title screen, was released by MORGOTH on the Evil Empire BBS Belgium on June 15, 1995, making it one of the first substantial early prototypes to be shared online. As the title may suggest, Sonic and Tails are the stars here, with the Chaotix cast nowhere to be found.

Sonic Crackers (referred to as ' Sonic Studium' in the ROM header) is a very early prototype of Knuckles' Chaotix, composed of different game engines swapped out using RAM coding.
