Level layouts are stored as .bin files.
For the Dreamcast version, they are in the /SONIC2 directory of the disc.
For the GameCube version, they are in the root of the disc.
Note: In the Gamecube version, these files are in big endian byte order! You'll need to convert them with SETswitch if you want to edit them with a program other than a hex editor, then convert them again before putting them back in the game.

File Name Layout

Level object files for levels 59 and under are always in the same format:

SETLLLL(_SS)(_C).BIN

Where LLLL is the level number, SS (optional) is the mode, and C (optional) is unknown. See below for usable values.

Listing of Levels

• 0000 - Test Level
• 0013 - City Escape

Modes

• 2P - 2 Player
• HD - Hard Mode

Examples

• SET0013_HD_S.BIN - City Escape Hard Mode

NOTE: If there is no file for a certain character in a level, it will load Sonic's file by default. If there is no file for Sonic, then no objects will be loaded. This can be corrected, though. Simply copy the appropriate file and rename it accordingly and the objects will appear in the level with that character.

The Object Format

Header

Every file starts with a 32 byte (20 in hex) header in the following format, where red is an unsigned integer containing the total amount of objects in the level.

00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

(If you ever forget the amount of objects, take the offset of the very last object, divide in hex by 20, and convert to decimal.)

Body

Objects are defined after the header in the following format:

00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

• The first byte, and part of the next byte are an unsigned short for the object type. You can find what value corresponds to each object here.
• This determines the lowest clipping level the object can appear on. 0 = Low (always), 1 = Normal, 2 = High
• This unsigned short is the X rotation of the object in BAMS (Binary Angle Measurement System).
• This unsigned short is the Y rotation of the object in BAMS.
• This unsigned short is the Z rotation of the object in BAMS.
  • Note: To convert from degrees to BAMS: (degrees * 182) = BAMS.
• This float is the X position of the object.
• This float is the Y position of the object.
• This float is the Z position of the object.
• This float is the object's first property.
• This float is the object's second property.
• This float is the object's third property.

Object Lists

The following are a listing of objects available to be used in levels. The number following the level name is the level number (for example, 0013 is City Escape).

Each object is given by its ID, codename (the verbatim text string from the level file that corresponds to that slot), and where it's known, a readable description of just what that object is. Apart from the first few stages that were created (Green Forest, White Jungle, Pumpkin Hill, Sky Rail, and Aquatic Mine), the team settled into a common scheme for shared objects, so the first 50 or so object IDs will usually be the same across levels.

Note: These lists may be incomplete or inaccurate. If you notice a possible improvement, edit it in!

Programs

If all that stuff above confuses you, there are two programs for editing objects.

DXEdit

Main Article: DXEdit

This is a simple tool that allows you to edit objects in a numerical format.

SETedit

Main Article: SETedit

This tool allows you to see names for objects, get position data from a running copy of the game, and has a simple preview window.
