Sonic_Chaos_(Jul_13,_1993_prototype)_Title.png

The July 13, 1993 build of Sonic Chaos has many more finalized or near-finalized things, including the title screen. However, there are still a few lingering differences and assets from prior builds.

General/Technical Differences#

There is no introduction scene.
Demos do not seem to be implemented yet. Sonic will just stand and do nothing when a demo loads up.
Pressing Start takes you directly to the level select.
Special Stages have been removed from the level select, therefore you cannot access them without hacking.
Sonic cannot do the strike dash move.
The Speed Shoes powerup still does not appear to work.
You start the game with 3 continues, regardless of if you are Sonic or Tails.
Crumbling platforms are still incomplete, but work better than they did in the June 30 prototype.
You cannot speed up the results screen tallying by holding down a button.

Graphical Differences#

The player select screen does not animate.
The ™️ text is missing from the title screen.
Sonic's sprites are identical to the June 30 build, although the different sprites are unused in this build.

Audio Differences#

Song ID	Name	Comments
$84	Invincibility	Closer to the final, but still higher in pitch and still endlessly loops.
$87	Game Over	Similar to the June 30 version, but with slightly different instrumentation.
$89	Stage Clear	Has been implemented, but is completely different here.
$8B	Final Boss	Similar to the June 30 version, but lower pitch and with different backing. Still higher pitch than the final version.
$8C	Master Robots	Much closer to final, but is slower and has different backing.
$90	Intro/Electric Egg Zone Act 3	Similar to the June 30 version, but more polished.
$91	Sleeping Egg Zone	Almost like the final, but not as polished.
$93	Aqua Planet Zone	Almost like the final, but not as polished.
$94	Continue	Lower pitch compared to the June 30 prototype, but still higher pitch compared to the final.
$95	Electric Egg Zone	A near-final version of the Electric Egg Zone music exists, but is only used when Tails collects the final Chaos Emerald after beating the final boss.

Sound IDs $96 to $9A are still unimplemented.
Like the June 30 prototype, the 1-Up sound does not play when hitting a 1-Up monitor.
There is no music for the title screen.
Like the June 30 prototype, Speed Shoes still affect the sound engine but do not do anything to the music.

Level Differences#

Turquoise Hill Zone#

To do:
Check the behavior in the June 30 prototype.

The Emerald Hill Zone-like trail makes a strange noise when you interact with it.

Gigalopolis Zone#

The boss introduction is different: he just suddenly drops in.

Special Stages#

Almost identical to the June 30 prototype, except the outside palette and the big ring graphics have been finalized. Though the big rings still don't animate.
