Hello everyone,

I hope I am in the right category for this, because I'm trying to extract the assets (especially the audio/sound files) from the game "Schlag den Raab" for PC, where all data assets are stored in .odau files and I can't find anything specific about that file format and I hope someone here can help me out with this.

There are a total of 41 files stored in the data folder, so are all files in the .odau format only and labeled from 001 up to 210.

I can also upload all files, if necessary (around 550 MB), but I hope one file is enough.

Thank you very much in advance.

It uses a 1-byte xor encryption - you can use the attached QuickBMS script to decrypt it.

The resulting file is a zip file with audio and other file types in.  Hopefully the other files will all be the same.

Thank you very much for this script, that did the trick and I was also able to extract everything from the other files too.
