Diarrhea

Daria's Inferno Audio Resources Repacking/Hacking/Extracting Application.

A command-line tool to work with the Hypnotix’es Daria's Inferno in-game audio.

The game utilizes a simple binary container that contains all in-game audio. It located at the {Game Directory}\audioLib\Audio1.dat binary file. Audio files are packed with their original file names (but the file extension is not included). The game loads a certain audio file using the file name as an identifier. Each audio file is a WAVE file.

The tool is compatible with the other games developed by the Hypnotix (e.g. the Deer Avenger 4 and the Who Wants to Beat Up a Millionaire), although some adjustments might be required (e.g. the binary container from the Deer Avenger 4 game does include audio file extensions in the file names).

Installation

No installation required. Just download the latest release and unpack files to a directory.

• list: List files on a *.dat container.

• packdir: Pack a directory with files into a *.dat container.

Usage example to replace in-game audio

1. Extract original in-game audio files:

   > Diarrhea.exe extract-all -i d:\Audio1_original.dat -p orig_ -s .wav -o d:\wav_files
   

   The -p orig_ option will add a prefix to all file names, while the -s .wav option will add a suffix (.wav file extension) to all file names.

2. Replace some files with your own versions. You might want to mark those files with the edited_ prefix to distinguish them from the unedited files.

3. Pack the directory back into a container:

   > Diarrhea.exe packdir -i d:\ wav_files -o d:\Audio1.dat --regex="(?<=_).*(?=.wav$)"
   

   The regular expression will remove all prefixes (marked with the underscore character) and suffixes (file extensions) from the file names.

4. Ensure that files are packed:

   > Diarrhea.exe list -i d:\Audio1.dat
   

5. Replace {Game Directory}\audioLib\Audio1.dat file with the generated Audio1.dat file. Now the game should play your custom audio.
