It's your update, man! I'm just facilitating, acting as a second check for install so JCompton knows it has been checked/tested/rechecked, etc. - you are doing all the real work. It is up to you whether the Korean translations are important enough to wait on or if you want to go ahead.
Just need a JCompton call on the sound mod integration, but the default position is "fixes and translations, and leave the C2 sound add-on as a separate mod". After all, the installation "problem" with the soundset is a cosmetic one. The installer is putting audio into override\override\mysoundclip.wav. The only reason to change it is for the chance to set up wavc files and unify a distribution fo rWin/ Mac/Linux, and stop folks getting worried about finding an override folder inside of their override folder. I think it is a PPG mod, not a WeiDU.org one, too, and JCompton's work, so he may want to keep it as a separate set of materials anyways.
