Sex 1 (PC)
The file "SEX.SAV" controls which pictures show up in the photoshop. Use a binary file editor to modify it. By changing byte $00 through $55 to the value $01, and also byte $1A to $1A, byte $38 to $1D, and byte $56 to $1E, all pictures are made available in the photoshop. These are presumably all the sexy scenes in the game.
