Proto:Sonic Chaos (Sega Master System)/July 13, 1993

This is a sub-page of Proto:Sonic Chaos (Sega Master System).

This article has just been started and needs the article basics added. Help us out and add them.

To do: Screenshots.

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

General/Technical Differences

• There is no SEGA screen.
• 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.

To do: Screenshots and comparisons to the June 30 prototype.

• 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.

• 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.
