Anti-Piracy

The game performs two checks to detect if a game is being played on a genuine cartridge.
If the first test is failed, the game will not load, hanging on a white screen.
If the second test is failed, the game loads, but the girls' affection levels will not be raised, thus preventing the player from going on dates, getting most of the girls' contacts, as well as receiving confessions. There's also a small chance that a girl will tell you that they aren't into pirates.
