Gigalopolis Zone

This is a sub-page of Proto:Sonic Chaos (Game Gear)/May 17, 1993.

This is the Zone usually the second to be presented in the game, in itself it presents several differences in layouts and objects!

General Differences#

• Collision in the tubes seems broken. When you jump, you get stuck into the tiles above the tube.
• Act 3 has a monitor placed in the beginning that is halfway offscreen.
• When Act 3's boss loads, the palette gets corrupted. For some reason, the boss writes to the palette lines twice: once to load the boss palette, and for some strange reason it overwrites the background palette line with Turquoise Hill's object palette.
• The Dangerous Ball Tower boss animates much differently and has many more segments compared to the final version. As a result, the Game Gear's sprite limit is often exceeded and some sprites flicker.
