Man this is a great game, I have many memories of it, as taking years until finally getting all the endings and CGs. One firsts h-games that I played. The game is very confusing and even the explanations can confuse you more than clear the confusion.
I have a walkthough of it somewhere in my CDs, I even have a hard copy of it in paper, but until the scanner is fixed I can't scan it. I do think that I also have a save of the clear game before the critical choices and with the full CG and ending clear somewhere in my CDs. I will look for it, but might take a while, I have literally hundreds of CDs and DVDs that I burned anime, manga and games.
Man now even I feel like playing it, where I placed my Dividead CD, I feel like getting Haruka again.
