Hi guys,
Recently, I start to translate some game from English to my native language (Vietnamese). I translated some type of H game use RPG MV, Ren'Py, ... Now I want to translate the game If You Love Me, Then Say So! which not use Ren'Py, then I don't know how to get the text. I think this game similar to Nekopara series (Visual Novel, Animated, Voiced). It have a lot of .arc file
Can someone help me by show me any tools to get the text of VN game which not use Ren'Py, or the way to get the text? I used Notepad++ to open .rpy text file for other Ren'Py game, but this game doesn's work.
I downloaded the game here:
