Guess i was doing the wrong thing, anyway thanks for the detail information, my specialty is pyth not unity and i mixed thing up.
nah it's pretty dang easy, just open the assembly .dll in dnSpy, look at either "road", "fera" and "sex", each of them will have "Communication", and in those you will see the buttons. Well if you know python already you can guess which one you need to replace, pretty much just those with
if button.text == "some japanese text":
You can take a look on the assembly .dll that I attach, and see which one I replaced, once you understand it, it's pretty easy to just do it on his other games.
