Finally unlocked all the CGs in the game, however there are a bunch of locked extras in the scene replay tab that I don't know how to unlock, also the Mother route CGs aren't in the CG view list for whatever reason.
Anyone have a clue how these extras are unlocked if they can be at all?
I haven't tried this myself, but have you tried entering the codes in the settings menu where it says codes? I know Sol Press has been posting some of the codes on their twitter recently.
