I can't seem to find it.

I am attempting to play one of the new Fairy Maze updates. I was told there is a way to translate it myself using some kind of file. However, I can't seem to find a thread about it here on how to do it. And Yes, I know a translated version just came out for it, however, when another update happens, I wish to know how to be able to translate it myself. So can someone help me?
