Ripping Animal Crossing for Gamecube / Extracting from an .img file

[skeddles]

I would like to rip all the sound effects from Animal Crossing for Gamecube. After extracting all the files, there appears to be one called audiorom.img which I'm guessing contains the audio. I can't find any methods to extract anything from this filetype, so any advice is appreciated.

I also tried ripping from the N64 version, but it includes a ton of garbage files and some seemed to be cut off, so I was hoping gamecube would be more fruitful.
