Professor Layton and the Diabolical Box

The second game in the first Layton trilogy, and the one with the best puzzles, but the most nonsensical plot. It was the first game in the series to get multi-language voice acting in Europe, where it was tremendously successful. It even later got a re-release in Japan with all of the 52 Wi-Fi puzzles unlocked by default.

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

The Japanese release used also a slightly traditional keyboard.

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 It would give a different error message, but its graphics everywhere else have been replaced by a copy of the “This name can’t be used” error graphics; not that it matters, since it never appears anyways in the localized versions.

Voice Acting
The European UK English version reuses the US dub, with a single difference: all the lines said by Luke have been re-recorded by a native British voice actress. The British accent imitation done by the American actress was reportedly borderline offending for the UK play testers. This change was carried in all the Layton UK versions, since the first game.

This game and all further localized Layton games have a different dub for each European language: there are French, German, Spanish and Italian dubs. The first game European version was a multi-language release using only the UK English dub.

The ending vocal song was replaced with an instrumental version, like in all Layton localized 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 trailer for Inazuma Eleven. The Japan-only re-release, "Friendly Version" (which has furigana over kanji for little kids), replaces that trailer with another one for Layton 3.

The second option from the main menu is called “Holiday in London” (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.

Unused Wifi-Puzzle
There are only 34 puzzles localized out of the 52 Wi-Fi puzzles from the JP version. One of the translated puzzles is never triggered normally, and thus remains unused: it is “Different Cats”, which has B as an answer and consists of a black model and five inverted-color mirrored patterns we must choose from. The rest of the puzzles have been mostly completely removed.

Puzzles with Unused Alternate Translation
There are two from the puzzles that were completely replaced in the US release, that had their original versions translated but got nevertheless replaced with alternate puzzles. They are still in the US version, unused, and go by the names: Bird in a Hole (Translated JP 56), and Boxes of Treats (Translated JP 75).
