@Sledgehammer:
Well, to find a sound that I want is no problem

, the file thing you mention is the problem

. The walther turbine uses the same sound file as the electric engine, you know, the submarine_electric.wav I think it's called, so what I mean is, is it possible to sort of expand the library of sounds by adding a special one for the walther turbine.....or maybe that's what you're trying to tell me?

I have to admit that I do not have experience with sound modding in SH4. Normally if I want to improve a sound I just substitute the wav. files. That SH.SDL file, is that a file that tells what sound that goes to what?
