OBD:Oni Binary Data

If you want an introduction to modding that starts from square one, you should read Modding Oni.

If you want a more friendly introduction to each type of game data, you should start with XML.

The OBD namespace is devoted to documenting Oni's binary data (.dat/.raw[/.sep] files), as reverse-engineered by dedicated members of the fan community. Needless to say, this is a highly technical area of the wiki, and knowledge of topics such as hexadecimals, pointers, and endianness is a prerequisite.

This database's information has been used by modders in such projects as:

• The Anniversary Edition
• Oni ni Kanabo
• The Binary Improvement Project
• OniFly

The knowledge documented here was also used to develop modding tools such as:

• OniSplit
• OniUnPacker (OUP)
• Oni Model Extractor (OME)
• Oni Trainer

Directory

• Format of instance files (.dat files)
• Format of raw and separate files (.raw & .sep files)

• Documentation of Oni's data types (integers, floats, etc.)
• Documentation of game data in Oni 2 (the Angel Studios dev build)
