I'm trying to figure out this format to get the music out of it, but obviously I know nothing about reverse engineering.
Going by the sound of it in-game I'm tempted to think it uses some form of ADPCM encoding... could anyone take a whack at these files and somehow extract the sample streams out of it?
Here's the music files: https://dl.dropboxusercontent.com/u/45822870/GunmetalMUSIC.7z
The demo of the game for debugging purposes can be found here, the format is identical as it's the same engine: https://dl.dropboxusercontent.com/u/45822870/GUNDEMO.ISO
It's in ISO format so one may load it into a VM for a quick xcopy deployment but this game runs just fine under any flavour of windows as it uses pure DirectX. (GunDX.exe obviously)
When running GunDX I'd advise enabling the ACT fixes "SingleProcAffinty" and "GlobalMemoryStatusLie" or the music wont play at all.
