doesn't work for KR retail version since they do not use .loc and while you are able to create an ads folder and put a .loc in it & update the resource ini to have the client load a different language, the server rejects connection and closes the client
First of all, why are you trying to do that in retail game. This is for private server, obvsly dont go work in retail, and KR doesnt use .loc, because the game its korean.. You just change the language in game option
