fate stay night rea nua version with sex scenes, extra and in japanese language

[saufall]

there is a patch available for rea nua version that restores sex scenes and extra but also by default translates the game into English. I like reading VN in Japanese so I wonder if there is a patch that restores the japanese text or is it possible to add the sex scenes and the extra to the rea nua version without the English translation patch.
