Oh ok, seems weird that the battle games can view them through playing normally but not the interrogation games.Lewd, rape, slave/ dark & love dialogues in interrogation games are only accessible through scene viewer.
As you know these games only have story mode 1 2 3 which are for progression towards ending & then there's extra mode that's for free play without restrictions & that is for normal story mode 1.
So no. It isn't possible to view them in any other ways than scene viewer.
About the extra mode, how much "free play without restrictions" are we talking about here?.
I think the normal story mode 1 are quite forgiving already in terms of difficulty, so what does extra mode offer?.
Also, thanks for replying to my earlier question.
