It's not good
to build on CachyOS (i only have this to test lmao) (it comes with zstd installed dw about it)
pacman -S base-devel cmake
git clone --recursive http://github.com/r1delta/revpk-mutated
mkdir -p revpk-mutated/build
cd revpk-mutated/build
cmake ..
make
based on revpk from https://github.com/mauler125/r5sdk and uses https://github.com/TinyTinni/ValveFileVDF this is mit licensed but i dont know how r5sdk licensing works so handle this at your own risk
if you put a WAV file or XMA file (if you're on an Xbox 180) into the VPK it will come out "all fucked up" and "distorted" (vitalized's words, not mine)
this is because of the Preload Section™️
SOLUTION:
Don't do that
