A pre-compiled binary is available for [download from my website](https://villermen.com/browser/?d=rscachetool). Just run the tool without arguments and it will tell you the available options.
- Combine sound chunks (.ogg) from a given archive into full-fledged soundtracks. It can even give them their in-game name based on another file from the archive.
- If you're aiming only at ripping named complete music from your cache these are your 2 golden commands: `rscachetool -e=40 -c` and `rscachetool -e=17 -n`.
- Extract all archives, combine music (including incomplete) and try to name the tracks `rscachetool -e -c -i -n`.
- Recombine sound 21713.jaga extracted to D:\cache and rename it `rscachetool -c -f=21713 -o -n=21713 D:\cache`. (Basically this tries to fix a file if SoX mangled it before.)
