- Example file
- CJBOPowerUp.BINA from dunno where (level 3, probably)
- Offsets
- Offsets are given with respect to RAW part start.
| Offset | Type | Raw Hex | Value | Description |
|---|---|---|---|---|
| 0x00 | 4CC | 43 4A 42 4F | OBJC | object collection |
| 0x04 | int32 | 18 02 00 00 | 536 | size to end of OBJC from 0x08, in bytes |
| 0x08 | int32 | 27 00 00 00 | 39 | object collection version |
| 0x0C | int32 | 28 00 00 00 | 40 | size of next (first) object (black outline) |
| 0x10 - 0x37 : first object (40 bytes) | ||||
| 0x38 | int32 | 28 00 00 00 | 40 | size of next (second) object |
| 0x3C - ... : second object (40 bytes), etc | ||||
- 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.
OBJC types
A given collection can only hold objects of a specific type, which can be :
|
- 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.
- That info used to be available as HTML HERE
- Now it's available as screenshots on the respective pages.
| ONI BINARY DATA |

| AKVA << Other file types >> CBPI |
| BINA : Binary data |
| TMBD << Other BINA >> ONIE |
| OBJC : Object Collection |
