• Install Python version 3.8 or higher

• Clone this repository:

  git clone <paste-here-repository-link>

• Install requirements:

  python -m pip install -r requirements.txt

• Run application:

  python -m igipy --help

• Also you can run sub applications separately:

  python -m igipy.qvm --help

Branches and repository

• master - Actual version.
• backup - First version (doesn't work but has many igi related resources)

Third party tools

In folder third party tools can be found tools from other developers.

• gconv - original game converter distributed by I.G.I 2 developers. Command line tool that run .qsc scripts.

• wav2wav - InnerLoop to Waveform converter developed by `guru1@bk.ru. This tool also can decode sound files encoded using ADPCM.

Usage

# Counts - scan directory and count extensions
python -m igipy abc counts D:\Games\IGI\

# Search - scan directory and list files that match pattern
python -m igipy abc search D:\Games\IGI\ *.wav

# WAV serialize - check if file match the format
python -m igipy wav serialize D:\Games\IGI\game_sound.wav

# WAV export - export WAV file as Waveform
python -m igipy wav export D:\Games\IGI\game_sound.wav D:\Files\IGI\game_sound.wav

# WAV export-dir - autoscan directory for WAV files and export them
python -m igipy wav export-dir D:\Games\IGI\ D:\Files\IGI\

Wiki

QVM files

Files with extension *.qvm contains compiled in-game scripts.\ They are compiled into bytecode for game engine virtual machine (like Java JVM).

Exists two known version:

• Version 5 - in first game Project I.G.I.
• Version 7 - in second game I.G.I.-2: Covert Strike

Source code of both version are identical but in compiled form are incompatible. Scripts from first game can't be used in second game (without conversion) and vice versa.

Related file formats:

• qsc files (Q Source Code) - source code of in-game scripts.
• qas files (Q Assembler) - intermediary file between qsc and qvm.
• qvm files (Q Virtual Machine) - compiled in-game scripts.

WAV files

Files with extension *.wav (as expected) contains in-game sounds.\ But do not confuse them with commonly used sound format Waveform.

Has signature (first 4 bytes of file) ILSF witch means InnerLoopSoundFile.

Have four different sound pack methods.

• RAW - not packed.
• RAW_RESIDENT - looks like not packed.
• ADPCM - packed.
• ADPCM_RESIDENT - packed.

ADPCM and ADPCM_RESIDENT appears only first game and at moment I don't know how to decode them.
