Regional Differences

This is a sub-page of Professor Layton and the Diabolical Box.

Logos and Title Screen#

Similarly to its prequel Curious Village, the Diabolical Box uses different logo's between the different version releases.

Level-5 Logo Changes#

The Level-5 logo screen is different between the Japanese and international versions, with international versions replacing the "Developed by LEVEL-5" and link to Level-5’s website with just "LEVEL-5 Inc".

Japanese versions	International versions

Mobiclip Video Codec Logo#

The original Japanese version shows an older ACTIMAGINE video codec logo, whereas later releases of the game show a mobiclip video codec logo. This is due to the original JP version releasing a lot earlier, before the rebrand happened.

Original JP release	Later releases

Title Screen#

There are some differences in title screen across all versions. The JP, KR and US releases all use a blue font for the title. When booting up the Japanese versions, rather than starting the sequence leading up to the title screen, the game immediately opens with a selection screen where one can choose between the game, London Holiday, and Inazuma Eleven's demo. This is why there is a 'back' button visible in the Japanese title screens.

Japan	Japan (Friendly Ver.)	US	Korea

All European versions of the game use a red font for the title instead.

UK	Germany	Italy

Spain	France	Netherlands

Name Input Screen#

The American version uses hand-writing recognition for the screen where the player inputs their name. It was, however, very clunky, which led to this feature being excised in the European and Korean versions, and all versions of the later games, for the traditional keyboard to make a comeback.

The Japanese release used also a slightly traditional keyboard.

U.S.	Europe/Japan

A profanity filter is used in the Japanese version, but nowhere else. It would give a different error message, but its graphics everywhere else have been replaced by a copy of the “This name can’t be used” error graphics; not that it matters, since it never appears anyway in the localized versions.

Voice Acting#

This game and all further localized Layton games have a different dub for Korean language and each European language: there are Korean, French, German, Spanish, Italian, and Dutch dubs. The first game for the Korean and European versions used only the UK English dub.

The ending vocal song was replaced with an instrumental version in the localized versions. This change was carried in future Layton games.

Japanese Sub Chapter#

In the JP version, when you boot up the game, there is a menu with three options: Main Game, London Holiday and a demo for Inazuma Eleven. The Japan-only re-release, "Friendly Version", replaces the Inazuma Eleven demo with a trailer for Unwound Future/Lost Future.

Original Japanese Version	Friendly Version

The second option from the main menu is called “London Holiday” (ロンドンの休日). This option is absent from all other localized versions, possibly due to all of its puzzles being used in the first game localization. It leads to a sub-chapter serving as a continuity thread between this game and the previous one's events.

The whole chapter takes place in a single room with 12 puzzles. They are:

1- How many 9’s? (W03 US)

2-Eye Of the Dice (125)

3-Worm in the Apple

4-Weight of Paper

5-Can you make the knot?

6-What number?

7-The Professor's Hat Box (W10 US)

8-Chicken and Chick (W18 US)

9-Island Tour

10-Door out of the Maze (W21 US)

11- Electricity Puzzle

12- Odd One Out

After finishing them all, getting 500 picarats in the process, the Professor reads the letter from his friend, which ties in with the beginning of the actual game. The sub-chapter ends immediately afterwards, and the game returns to the main menu.

It is worth noting that the localized version is based on the original version: it has unused menu graphics for Main Game, London Holiday, and the Inazuma Eleven trailer, although the data for the actual London Holiday mode has been removed.

Character Design Changes#

Felix had his design changed between the Japanese version and international releases. His skin was made lighter and his lips were no longer emphasized. Interestingly, his pose on his character information page was also changed to look less aggressive.

Japanese versions	International versions

Name Changes#

Character Names#

Many names were changed between the Japanese and international versions. The returning characters had their names retained in the Japanese and international versions.

European Version#

The US English and European English revisions have several name differences.
