This is an old Java program I wrote to extract the VAG audio files of Jak and Daxter: The Precursor Legacy from VAGWAD.ENG. The extracted files are just named ordinally (1.VAG, 2.VAG etc.) since there seems to be no simple way to match them to the file names stored in VAGDIR.AYB, and those file names are not at all descriptive anyway.

To operate it put a copy of VAGWAD.ENG in a folder with the compiled jar and run it :)

You can use ffmpeg to convert the extracted VAG files into a more common audio format.
