I just picked up Shipwreck for $1 on sale and decided I really liked two of the tracks. Like other MonoGame ports, it uses the same XWB-format bundles for music as XNA games on Windows and X-Box do, so you need unxwb to extract them.
Just run it like this and you should get a bunch of audio files dumped into the current working directory.
unxwb -b music.xsb music.xwb
For those who aren’t running Linux, aren’t using an x86-compatible processor, have older system libraries than Ubuntu 12.04 LTS, or don’t trust binaries off random websites, here’s how to build from source on a Debian-family distro:
sudo apt-get install build-essential zlib1g-dev
If you want to replicate exactly what I provided, make sure you’re building on Ubuntu 12.04.4 LTS for x86_64 and replace that last step with this:
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install zlib1g-dev:i386 advancecomp
You can start from either the contents of the original zip or mine. As long as you add my Makefile,
make dist should produce the same result.
