you can fine a PDF online wich gives you detailed info of the checks. This is the best i can give you right now. Go trough this and make some notes of requirement scenes. Those that are in later checks as requirement. When you reach them, save the game beforehand so you can go multiple paths and trigger each event. Also recommend saveing after each chapter for each path for when you mess something up. Split them on multiple sites so you can differ the paths later on. Takeing notes in these games is never a bad thing.
