SonED2 Sonic 1 Special Stage Editor

The Sonic 1 Special Stage Editor is used for editing the map layout and starting position data for Sonic 1's Rotating Special Stages.

The map layout is formed by placing "Objects" onto a 24x24 (pixel-measurement) grid. The images and descriptions displayed in the editor are set up through "Sonic 1 Special Stage Object Listing Files", which tell the editor how each object should be represented graphically. Those files may be altered and expanded upon as described by their own documentation.

This editor is capable of animating the "Objects", so that animated walls can easily be placed in the desired order.

This editor is made up of two editing modes:

Layout Editing Mode:

• Status
  
• Drawing to the layout
  
• Selecting Object Type
  
• Switch Editing Mode
  

Start Position Editing Mode:

• Status
  
• Moving a Player Start Position
  
• Switch Editing Mode
