It's just a checklist if you've seen each ending. It's not coded to jump to scenes like in KJH3; there are like a half does reasons why I couldn't have it do that.
I had a look at the code and I see what you mean - some of the endings depend on the game state, or aren't clearly delineated. It's possible though. I hacked together something that works for all the endings, and can send it to you if you like.
