* SequelDifficultyDrop: Or, in this case, remake difficulty drop; the original Famicom cases that the DS release features remakes of have a set time limit, but since the remakes lack it, there's no danger of getting a bad ending/game over outside of Unleashed.
* {{Woolseyism}}: The dialogue in ''Jake Hunter Detective Story: Memories of the Past'' completely nails the FilmNoir vibe of the game, complete with antiquated lingo taken straight out of the genre's heyday.
