This fixes https://github.com/kichikuou/xsystem35-sdl2/issues/45. The behavior when the contents of link table differ between ALD volumes is different between System 3.8 and System 3.9, and System 3.9 uses the link table of the first volume. The MangaGamer version of Rance 5D depends on this behavior. As far as I know, the only game that depends on the System 3.8 behavior is Child Assassin (in Alice CD 2.50). Considering the additional complexity, we do not implement switching to the old behavior.
