Differences between the book/movie and game
- This is by far the most faithful version to both the film and the book.
- This version, along with the Playstation and PC versions, features Ron and Lockhart accompanying Harry into the Chamber of Secrets like in the book/movie.
- Ron doesn't go into the Forbidden Forest with Harry in any of the games except in this version. Nevertheless in the PC version Ron appears in the initial cutscene of this level and remarkably says: "You'll have to brave the Forbidden Forest alone."
- This version, along with GBA, PS1 and PC versions, does not feature a Whomping Willow located at the Forbidden Forest.
- In the book and the movie, Harry kills the Basilisk by stabbing the Godric Gryffindor's sword into its mouth. Likewise, this is the only video game adaptation of Harry Potter and the Chamber of Secrets where Harry uses the sword to stab the basilisk, whereas in all other versions of the game, Harry bizarrely has to use the sword to fire/reflect a beam of energy towards the basilisk.
- In the book and the movie, Harry stabs the diary with Basilisk's fang. In this version he also stabs it, but using the sword. Whereas in the other versions the diary is destroyed when the Basilisk lands on it or when it drops poison over it. By sheer coincidence, this would have worked in the book, as by that time, the Sword of Gryffindor was imbued with Basilisk venom, giving it the same power to destroy the diary Horcrux.
- The term "Muggle" is consistently avoided in this game, with terms such as "Non-magical people" and "Non-magical Studies" being used instead.
Behind the scenes
- This is the first game in the series where you are able to control multiple characters in any capacity. During the turn based combat sequences, the player is able to control the moves of all members of the party, predating the video game adaptation of Harry Potter and the Prisoner of Azkaban's commonly advertised feature of being the first game in the series to allow the player to control all three of the trio. In addition, Lockhart can briefly join the party while disarmed (who will shrug if a spell is attempted), and whose only unique move is to sign an autograph, which freezes an enemy for a turn.
- In the part where Harry, Ron and Lockhart are in the Chamber of Secrets, there is a potential glitch. When the 3 fight in a magical encounter and lose it, the screen resumes to Harry on the other side of the snakeskin and when you move on to the Chamber of Secrets, you still have Ron and Lockhart in the group and during the fighting of the Basilisk, Ron joins Harry and Fawkes in battling the monster and later Lockhart is said to have lost his memory without his backfiring Memory Charm having happened.
- This was the last game released on the Game Boy Color in North America.
