Layton's Mystery Journey: Katrielle and the Millionaires' Conspiracy (Nintendo 3DS)

Layton's Mystery Journey: Katrielle and the Millionaires' Conspiracy is a game in which the well-known Professor Layton apparently goes missing, and all the focus is shifted to his daughter and the detective agency she runs in London. This spinoff in particular has a bit of notoriety within the fan community, as no one can really decide whether it's good or not.

While Mystery Journey initially started out only on 3DS and iOS/Android, it would later be ported to the Nintendo Switch twice (one being a normal Deluxe Edition, and the other being a Japan-exclusive Deluxe Edition+ that allows the player to change the characters' voices to the ones used in the anime).

Error StringsA lot more than the previous games.

Unused Graphics#

Map Placeholder#

lt6_b.fa/gmp/g4540.xi is a placeholder graphic that reads "Area: River Thames; Guide Map: Clara Edwards". "クララ・エドワーズ号"/"Clara Edwards" is the Japanese name of the Thametanic, as well as the Japanese title for the track that plays while aboard it, meaning that this likely held the spot of one of the maps from Case 08.

DLC Placeholder#

This image is repeated a total of 12 times in the lt6_b.fa/menu directory. It falls under the dlc_fas files numbers 00 to 06 and the dlc_room files numbers 00 to 04. The text reads "DLC image (temporary)".

Logo Movie Placeholder#

lt6_b.fa/menu/level5_u_TX.xi is a temporary image of Level-5's logo that would display with the company names at the beginning. It would later be replaced with the animated version. The text says "※A movie will be displayed. This is temporary material".

Early Synopsis Touch Screen#

lt6_b.fa/menu/synp_bg_l_TX.xi is a Touch Screen background for the synopsis that shows when the player starts the game up. Interestingly, this is from when the game was still called "Lady Layton".

'Hidden Door' Symbol#

In Layton games, there's typically 6 different kinds of extra content in the 'Top Secret' Bonuses section: Profiles, Art, Music, Voices, Movies, and a password-locked Hidden Door. Mystery Journey did not include the Hidden Door bonus, and only had the other 5. A symbol for it still exists alongside the others in lt6_b.fa/menu/s_menu_ani_a.xa/002.xi though, suggesting that the game was initially going to have one. This is the only existing graphic in the files for this bonus, as there are no unused UI elements or other sprites.

Cases 13-16#

In the game's story, there are only cases numbered 0 to 12. However, inside lt6_en.fa/menu/en/ctr, there are ept_TX files of the case titles with numbers going all the way to 16 (with exceptions for the ones numbered 97, 98, and 99, which are just labels for the Special Puzzles, Bonuses, and the 'Pick a case to tackle from the board' text). Unfortunately, numbers 13, 14, 15, and 16 just say "予備エピソード①", "予備エピソード②", and "予備エピソード③" ('Preliminary episode' 1, 2, and 3), with 15 and 16 using the same graphic.

They also have correlating ept_number_TX files, that state which number case it is.

Unused Models#

From the lt6_b.fa/chr directory.

Luke and Flora?#

Nestled between Britannias and Ratman are c220.xc and c221.xc, which appear to be placeholders for character models. They are nothing but flat human-shaped textures with no animations. The most intriguing part, however, is how the names on their "torsos" are ルーク and アロマ, or rather Luke and Aroma (Flora's Japanese name). These could have something to do with Katrielle's 'Luke Lookalike' and 'Floral Finesse' outfits, although those are already present as c115.xc and c113.xc respectively and grouped with other wardrobe models, so their true purpose remains unknown. One theory could be that adult versions of Luke and Flora were initially planned to be included, but were scrapped pretty quickly.
The textures (and pretty much entire models) are as shown.

Unused Cinematics#

Present only in the Japanese version is a leftover cutscene from the first Yo-Kai Watch game under the name of m099.moflex, this one being the intro to the Japanese version of the game. Based on the filename and the absence of an .xq code file (which would run it), one possibility is that it could have been used for testing at some point in time.
MobiClip cinematics and their audio are kept separately, and this one doesn't have any correlating audio files, so unfortunately it is dead silent.

In the game's Android version files, there is an unfinished cutscene called m022.mp4. Several of the frames are just sketches with annotations. This cutscene was removed in the 3DS port, although the m022.moflex file does exist; however, it displays a black screen when played.

Unused Text#

'...But what does it mean?' This game has text or audio that needs to be translated. If you are fluent with this language, please read our translation guidelines and then submit a translation!

From the lt6_en.fa/txt/en directory.

'NOT USED'#

22_002300.xs is the only file in the 22 subfolder, which contains the text for the current task(s) the player has at hand during the game. This line seems to stand out among the rest, and it reads:

*** NOT USED (REPORT IF DISPLAYED)
***

Secret Nazotoki Room#

40_008300.xs appears to contain text for a 'Secret Nazotoki Room', similar to what Azran Legacy had. Neither the overseas nor Japanese versions ended up having one, and there are no graphics or code related to the Secret Nazotoki Room in the game files (except for a leftover .xq file for the one from Azran Legacy), so what it may have looked like or what puzzles it would have provided will likely - and unfortunately - forever be a mystery.

The name "レイトン７" ("Layton 7") in the first two password-entry prompts appears to be another placeholder title used for the game before it was changed to Lady Layton and then finally Layton's Mystery Journey. Oddly enough, this name was also used for an unreleased mobile game announced a few years prior, but whether or not the two have any connection is unknown.
The third prompt is likely talking about another Inazuma Eleven game, since third password in Azran Legacy was also related to that.

Hidden Door#

40_09600.xs has text related to a Hidden Door, which -- as previously stated -- the final game didn't end up having, with the only graphical evidence being the symbol for it. It claims that if the player meets the right 'conditions' in Azran Legacy, the door of Layton 7 will open. The method of unlocking the Hidden Door likely would have been similar to the one for the previous game, where the player had to go to the Daily Puzzle section of Miracle Mask and press the 'Download' button, which would then detect the Azran Legacy data on the system and unlock its secret contents. (If the player owned them both as eShop downloads, however, they would automatically detect each other.)

Hidden Door Gallery#

40_009610.xs is text for a special art gallery that the unused Hidden Door would unlock (again, quite similar to the one in Azran Legacy). It's obviously very unfinished though, as everything seems to just be placeholder text.

Azran Legacy Leftovers#

Root Directory Name#

Internally, the game is referred to as lt6 -- the exact same internal project name that Azran Legacy uses. The most likely case is that the developers just took the original Layton 6 project and used it to make something new.

.xq Code Files#

lt6_a.fa/seq contains all of the code for the mini dioramas, Azran Legacy's Secret Nazotoki Room, and Azran Legacy's Hidden Door.

Profile Character Scripts#

lt6_a.fa/res/scrt/lt6_scrt_chr.xs is a script for the Profiles bonus, which has name labels for the character artwork/models in the sixth game.

Graphics#

Story Puzzles#

Present in lt6_b.fa/nazo/ani/n001_num.xa are sprites from Azran Legacy's puzzle 'Golden Butterfly'. They are stored alongside the numbers used in Mystery Journey's puzzle 'Alien Attack'.

file:LMJ- n001_num.png

Daily Puzzles#

lt6_b.fa/img/bg_daily_eve.xi is a background from the Daily Puzzle service, used when Granny Riddleton is talking to the player.

file:LMJ- bg_daily_eve.png

Demo Leftovers#

There are two files in lt6_b.fa/menu called trial_thank_a.xi and trial_thank_b.xi, but they're completely empty. Mystery Journey never had any kind of playable demo, so these are likely from the one for Azran Legacy.

Regional Differences#

Cutscenes#

Cutscene 01#

In the Japanese version, part of the opening cutscene features the song "Girls" by Kana Nishino. The vocals were changed to a violin for overseas copies, likely to avoid having to translate it into multiple different languages.

Cutscenes 04 and 26#

To do: Check the other European languages.

Cutscenes 04 and 26 were altered in the English versions, solely due to the change in Sherl (originally Sherlo) and Felicity's (originally Lilia's) names during localization.

Cutscene 04

Cutscene 26

Character Names#

To do: Finish this, and add the names from other European languages.

Secondary Internal Name#

While it's already been addressed that the root directory folder refers to the game as lt6, one of the sound archives and a script for the Daily Puzzle service calls it by another name - lmj1, most likely standing for "Layton's Mystery Journey 1".
