SFX ripping/decoding/dumping features?

[Shonumi]

I think a few common audio formats that games used are supported by some audio software (we can't help you in that regard since you haven't told us anything about the game you're interested in) but it could very well be a custom audio format of the developer's own making. It would be possible to reverse engineer it, but that doesn't mean it would be a trivial task.
