Further revisions of the game would gradually remove/improve the 'TIME ATTACK' option and ultimately replace it with the 'TRAINING' option. But very rarely, for reasons still unknown, selecting this option will occasionally boot into an unused menu specifically for 'TIME ATTACK'. Normally, selecting the 'TIME ATTACK' option on the title screen brings you to the prototype's usual rudimentary character select menu and the 'ATRACTION SELECT' screen. The Combi Catcher is even more barebones, not even a level instead, whenever the player exits the hub to the right, this screen pops up the first question mark is Mighty, the second question mark is unselectable (again, likely Tails) and the third question mark is Espio upon selecting your partner, a level select popup.Ī strange oddity occurs in this prototype. Incredibly bare bones at this point there's an empty slot after Knuckles (likely meant for Tails, see below) and the player has the option to choose Heavy and Bomb, which are only Combi Catcher characters in the final. Selecting 'No Save' will start the game normally.

Selecting file 1, 2, or 3 may place you instantly in the World Entrance with two Espios.

Level numbers in the save files do not render properly.

Controls are reversed ( Up moves down, Down moves up).

The save menu is in an earlier state than the title and is very buggy: A + B + C + Start will exit the Jam Out menu. Buttons on the D-Pad can be held to change between sound banks.

In Jam Out mode, press A, B, C, or Start to play the many different PWM samples.

Cheat menus are accessible by highlighting OPTION, then pressing A + Start for Color Test, C + Start for Sound Test (with preliminary graphics), or B + Start for Jam Out mode (which acts similar to Toejam & Earl).

Selecting OPTION brings you only to the Sound Test, which is a very basic screen: a black background with white text.

The main menu is where the copyright text would be.

The Chaotix logo has no palette cycling, nor does it have the TM mark.

The main characters are absent, and their graphics do not exist in the ROM.The title screen is in a somewhat preliminary state: The Sega logo lacks the 'TM' and instead of zooming in, the Newtrogic High image fades to black, leaving the Sega logo in the dark for a few seconds. The Sega screen uses a promotional image of Newtrogic High Zone, the final changed this to the Game Over/Level Beat screen instead.
