No "universal" unlocker will work for this game, this game uses specific persistent variables to display the gallery, the gallery script check if those values are set to "True" and those values are only set once you watch a scene, for that reason the specific variables don't exists until they are set to "True" so if you want them to be set you need to manually set each of them. that is what I did and what the dev did on the original posted. bcs those variables don't exist until they are set there is no way to loop and set them automatically.
