Well, I've tried to replay some games form
SchoolDays, but every single one of them started at the begining of the game... Well maybe it should be like this, but the display is spoiled as always, so... But, when I simply loaded one of these (unfortunately I don't remember which one), there was something like opening, and after that the display has been fixed. Due to this maybe I will be able to get through the game... Of course it depends on how much such "openings" are in it. But anyway thank you a lot!
Oh, and I've found this website:
reversed factory :: [Eng] How to translate School Days using AGTH to hook DLL in real-time (Overflow). Anybody tried to translate it like this?
And once again, thank you very much Ichigo!
