I'm only download nutaku version, extract, open Kamihime Player 1.0 PC -> game -> nutaku, run 1_download_assets.cmd, 2_build_rpy.cmd, 3_write_config.cmd. Then open the Kamihime_Player.
At first I can't check the setting because there aren't any text appeared in the References page, only left menu have text: History, Save, Load, References, Main Menu, About, Help, Quit, Return, the right page only have black screen and blue bar, none text. So don't know what is it use for, but after read your answer, I try to increase all blue bars to max and it have voice now (but still annoying because it doesn't have text)
By the way, because the amount of data is too large, it's take very long each time I run the Kamihime_Player, if I want to separate them to 3 different folders, then which file I must cut?
