Yeah, I agree that by now it doesn't really matter to Konami if a patch is released or not. The game is already old, not easily available, and if someone wants to download the game, why would they download the PC version and not the PS2 one?
For the Japanese one, all the scattered stationery is the freebie that was handed out at stores (I think) and came the game. Dunno if everyone that pre-ordered got one though. It's kind of like that heartwarmer thing. :P
I've never seen the horizontal boxes before. I wonder if that's what was in the box! And that manual looks like it's a hard-cover! D:
