To be honest, there are two things that I couldn't find it in the game, which are "The Secret Footage of Bonfie and The Embarrassed Pose of Frenni". About the Secret footage, is it when you repair and unlock the camera?

Oh I see… For the Bonfie footage I believe I heard you need a certain amount of “coding” research before night 5 to unlock that one, so I haven’t found that one myself either but i am sure someone in the community would love to help you out with that.
Also very useful guide you have posted I will definitely use it for my play through.
