- General layout
- The collection's header (first 16 bytes) and layout is common to all 16 OBJC types (see below).
- The size of the whole collection is announced at 0x04 (int32), followed by the collection.
- Unlike ONIE and TMBD (which are arrays), OBJC announces the size of every object (int32).
- After the last object, the end of the collection is signaled by a null next object size.
- Object header
- All objects start with the following header:

- Blue Box Beta "revelations"
- A German Mac Beta version was released as part of a compilation of old Mac games.
- The version contained extra WMDD files, part of Oni's developer GUI.
- Supposedly it allowed developers to edit OBJC files while running the game.
- Those menus provide additional information about the structure of a few OBJC types.
