OBD:Oni Binary Data

If you want an introduction to modding that starts from square one, you should read Modding Oni. You should start with XML if you understand the general workings of game engines and want a more friendly introduction to each type of game data.

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:

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