It works, yes, but it doesn't seem like there's a lot of new scenes that have been added. If I had to guess, I'd say the new update perhaps has specific 'ending' scenes, but since this mod doesn't have an 'ending' category, it only shows the regular specific character ones. No idea if I'm right or not though.
Skimming through the game's gallery code, it looks like this mod works as it should. Anything that's in the gallery is unlocked, and that does include any endings that are there.This may need a final update with endings included.
Of course, if there are specific issues you can name, please do let me know so that I can get on it.
