^Hm? Proper recollection room? As in, something that doesn't require you to beat the game, first? First things first, the second game has that room, too and although it has been a while since I played the second chapter, I remember its recollection room working like this:
- There's a circle in front of the character's sprite;
- You go there and press Confirm/Talk, then you get pretty much teleported to the area where the event takes place (or the closest one to it);
- All you need to do to watch a scene (or watch it again), is purposely fail the event, or lose the boss fight/etcetera…
- As for the night scenes/visits, the recollection room actually gives you the chance to see also those that you didn't manage to "unlock" while playing (for example: thanks to my limited knowledge of Japanese, I've never understood what I needed to do to have the Sniper Lady pay Hakunen a visit, but I just need to go to the recollection room, talk to her+pick an option and then go back to sleep).
Last, but not least, the developer should have included a 100% save file for the second chapter, too, you can use that.
