Hi Jochi,

no this is totally different to the sound swapper that Tosa made.
This add-on is for those who don't have STW, don't have it installled, don't want to use the swapper, have failed to use the swapper, etc.
It contains all the sound files needed. (that's why the download is so big)There's no need for a STW install.
Install routine should not cause any problems as long as pointed at the main folder of Medieval.
