The Coded Map of the City Case

Situation
After visiting an exhibit on hidden treasures Conan and his friends find a piece of paper with symbols and the word "Oro" written on it. A treasure hunt ensues but does not discover much. Conan, initially not interested in the children's treasure hunt finally realizes that the paper is a treasure map after learning that "Oro" means gold in Italian. That night, Conan determines that the symbols refer to neon light signs on buildings.

Manga to anime changes
Main article: List of differences between the manga and anime


 * An entire portion of the story is left out of the anime where Ran takes Conan, Genta, Ayumi, and Mitsuhiko to Tohto Tower. She recalls a time when she and Shinichi visited the tower and when he bought her a cold drink, which he put up to her cheek. Conan does the same thing, which prompts her to ask him about his true identity (as the manga version takes place after the The Shinkansen's Bomb Case). Conan responds by stating that he is Kamen Yaiba. The scene in question would later appear (ironically) at the begining of the fourth movie Captured in Her Eyes which Ran has a flashback too.
 * In the manga, Genta envisions that the Italian gangsters will shoot him, and imagines himself lying in a pool of his own blood. The anime substitutes a less graphic and more stylized image, with a miniature Genta being riddled with colorful, cartoon-like gunshots.

Remastered version
On June 6, 2009, a remastered version of the case was aired
