Persona 4 is the fourth installment in the Persona series (part of the larger Megami Tensei series) and the second to be on the PlayStation 2. It was a big hit, especially in western territories, and it was enough to create some side games, including two fighting games. It later got an expanded re-release on the PlayStation Vita as Persona 4 Golden.

Sub-Pages

Bugs

Unused Voice Clips There's a lot of them!

Unused Dialogue Unused (and unrecorded) lines, signs of an unused gas station part-time job, and more!

Debug Logging

Within the game are two stubbed printf functions which would have logged various background information to a debug unit. This logs information such as files and maps loaded. It would also report errors if any occurred. To re-enable these, apply the below codes.

USA codes:

Fix Atlus's printf Function
20440B68 08109132
20440B6C 00000000

Re-enable Debug Error Messages
2043BB48 08109132
2043BB4C 00000000

• Fix Atlus's printf Function calls scePrintf. The function in this game that would print debug messages is useless and doesn't do anything.
• Re-enable Debug Error Messages calls scePrintf to print error messages if any occur. The orignal function is stubbed.

If you are playing the game on a regular PlayStation 2, you will need to use a TOOL, RDB, or a debug version of OPL to view the logs. If you are playing on an emulator, you can see this information by enabling the option "Show Console". Below is an example of what type of information gets logged.

Unused Graphics

Dialogue Portraits

Placeholder	Kenji Tomochika

A silhouette dummy portrait with "temporary" written on it. The silhouette belongs to Persona 3 character Kenji Tomochika. This dummy portrait is used as a placeholder numerous times for various characters.

Unused	Final

Yosuke Hanamura. His early portrait lacks proper shading, and the Yasogami High symbol is missing from his uniform jacket.

Unused 1	Unused 2	Final

Two unused portraits for Yukiko Amagi, both quite close to the final design. The proper shading is missing and the colors are brighter. Yukiko's collarbone shadow was raised for the final portrait. The first unused portrait comes with a blinking frame.

Unused	Final

Kanji Tatsumi. This is a flat color sketch version of his portrait, missing many features compared to the final design.

Unused	Final

More Kanji, this time in a yukata. The difference between these portraits is minimal, but the unused version is slightly zoomed in and lighter in tone.

Unused Sketch	Unused	Final

Two unused Rise Kujikawa portraits. The first one is a flat color sketch in the same style as Kanji's. The second is much closer to her final design, but the proper shading is missing, the colors are much brighter, and the portrait as a whole is zoomed out a bit.

Unused Sketch 1	Unused Sketch 2	Final

Early Ryotaro Dojima portraits. The second is much closer to his final design.

Unused	Final

Saki Konishi. This unused portrait is similar to Kanji's unused yukata portrait. It's slightly larger and has a lighter tone.

An unused Flat Teddie portrait.

Regular portrait of Ms. Mayumi Yamano, the first murder victim of the story. Copied for the news image of her, but this unaltered version goes unused.

An unused Shadow Adachi portrait.

Three unused portraits for Kanji, Rise, and Naoto. All of these portraits have each character's normal face, but their Shadow version's clothing (or lack thereof).

(Source: Original TCRF research)

Dungeon Cut-In Portraits

The portraits in this section were found among some cut-in graphics for the navigator when exploring dungeons. The larger square ones may have been intended for non-dungeon scenes, though, as is the case with Yukari's in Persona 3.

Two cut-in portraits for Naoto. Naoto's chin in the second portrait appears to be modified to some extent.

A similar set of portraits for Rise. The squished portrait here has some splicing going on, which is most evident on Rise's cheeks.

Unused	Final

This third portrait of Rise features a lighter hair tone and lacks a gradient on her skin. It's also vertically squished in comparison to the final portrait.

A portrait for Yukari Takeba, along with a backing visual effect. This portrait was used in Persona 3, but cropped to some extent. There are multiple copies of these images.

Battle Cut-In Portraits

Unused Cut-In	Concept Art

A placeholder cut-in portrait of Kanji, which is a colorized and cropped version of some concept art seen on the right.

Unused Cut-In	Concept Art

A placeholder cut-in portrait of Rise, with a striped background. This is a cropped and recolored version of some concept art seen on the right.

Early
Final

An early close up cut-in portrait for Yukiko.

A close up cut-in of the Persona 3 protagonist, accompanied by a visual effect.

Persona Portraits

Unused	Final

An unused version of Ongyu-Ki can be found duplicated numerous times throughout the various Persona portraits. This unused version is darker, and is missing a yellow gradient overlay used on many final portraits.

Placeholder & Test Graphics

A battle-related graphic that says "trash".

A weather/news-related graphic that says "temporary".

Battle graphics for a generic-looking test party member. In Persona 3 FES, there are mock-up images depicting a generic party member with the same design.

A dummy wall and floor texture respectively. These appear in the dungeon archives for Marukyu Striptease, Void Quest, Heaven, and Yomotsu Hirasaka.

A simple dummy texture.

This test texture translates to "Welcome to the boss room! (Temporary)".

Miscellaneous

A dungeon speech icon for the protagonist. Since he never speaks while exploring dungeons, this image is never seen.

Texture Oddities

These two textures are used for some hologram projections in the Secret Laboratory dungeon. These are actually excerpts from a French Huffington Post article about a Japanese agricultural minister who resigned.

The entire section of text below is used in the second texture. The text in the first texture is bold:

Le premier gouvernement formé par Abe avait collectionné scandales et faux-pas, et le dirigeant conservateur de 52 ans a procédé à un remaniement, lundi dernier, pour tenter de regagner en popularité après la défaite de la coalition au pouvoir dans les élections du 29 juillet, qui ont donné à l'opposition une majorité à la Chambre haute du parlement. Le ministre, Takehiko Endo, avait avoué samedi que l'organisation qu'il avait dirigée avait illégalement touché 1,15 million de yens (9.900 dollars) de fonds publics sans en informer Abe avant sa nomination. Endo, 68 ans, qui avait rechigné à accepter ce poste marqué par de précédentes défections, a confirmé sa démission lundi lors d'une conférence de presse donnée après un entretien avec Abe, dans sa résidence officielle. Le premier ministre de l'Agriculture d'Abe s'était suicidé à cause d'une autre affaire. Le deuxième avait été limogé en raison d'allégations d'irrégularités dans ses comptes de campagne. UN ÉTAT DE GRÂCE FRAGILE Deux autres ministres du premier...

The text in the first texture translates to:

The minister, Takehiko Endo, admitted on Saturday that the organization he directed has illegally obtained 1.15 million yen (9,900 dollars) of public funds without informing Abe before his nomination. Endo, 68 years old, who begrudged his position marked with previous defections, has confirmed his resignation at a press conference after an interview with Abe, in his official residence. The prime minister of the Agriculture of Abe has committed suicide because of another case.

Persona 3/FES Leftovers

To do: Sub-page this and add the remaining hundreds of leftovers.

In addition to the content below, Persona 3's entire battle archive data (totaling over 700MB) was put in Persona 4 as filler data to pad out the disc.

A full size portrait for Yukari Takeba. Comes equipped with an over-saturated blinking frame.

Dungeon speech icons for most of the crew.

An image of Orpheus, the Persona 3 protagonist's main Persona.

Unused Models

A test model made of cubes named DOBJ000. It can be found in data.cvm\FIELD\GRMD.

A simple cylinder model named "base".

A dummy model with bones and joints. Its file name is "editor". This is actually a default biped model for use with the programs CAT (Character Animation Toolkit) and 3ds Max.

An unused white shadow model found within a number of unused dungeon maps. Shadows are normally colored dark purple. These white shadow encounters contain extremely high-level enemies.

Unused Music

Almost the entirety of the Persona 3 FES soundtrack is contained on the disc, well beyond the ones used during the school trip to Tatsumi Port Island. We could put them all up here, but it would just effectively be 90% of Persona 3's soundtrack.

Strangely, this also includes the "Burn My Dread -Reincarnation: Persona 3-" album version of "Deep Breath Deep Breath"...which isn't a leftover from Persona 3 FES.

An early version of "Burn My Dread" labeled THEME.ADX found in Persona 3 also exists in Persona 4. It goes unused in both games.

A song from an unknown game. This also appears in Persona 3 FES.

Unused Videos

The intro video to Persona 3 can also be found alongside the other video files, labeled as P3CTOP.SFD.

Unused	Final

An unused version of the credits background video was left in the game, named P4SR.SFD. It contains the following differences:

• Character portraits aren't finalized.
• Persona portraits are sketch versions.
• There is no audio track.
• Anime cutscenes are substituted with the TV transition video, and "dummy anime" text on the bottom right.
• Characters are presented in a different order:

The Persona used by the true killer in their boss battle, Magatsu-Izanagi, exists in the game data as an unfinished Persona of the Fool Arcana. It has stats similar to those used in its boss battle, but no skills programmed. It also has no description listed in the Compendium. In Persona 4 Golden, he was added as a full-fledged Persona usable by the protagonist, but reclassified under the Hunger Arcana.

There are also 4 blank dummy Persona slots: 02B, 034, 0B4, and 0B5. These (as well as the dummy slots at the end after all the other Personas) appear as Fool Personas with no data, using the portrait of Ongyo-Ki and the 3D model of Slime. They can be used in regular fusion as Fool cards.

Unused Enemies

This page or section needs more images. There's a whole lotta words here, but not enough pictures. Please fix this.

The Maya enemies from Persona 3 are still in the game and retain their models and animations, but they all have dummy default values and no skills. There are also four additional Basalt enemies that do have actual values programmed in, as well as a monster used for testing rare golden Shadows.

Introduction

This text was intended to be shown after selecting the difficulty before starting the game. For whatever reason, it's not used.

Thank you for purchasing Persona 4.

Before you begin the game, we’d like to
ask you, the player, for a favor.

This game has several mystery-style
factors that involves finding the killer
behind a series of heinous murders.

Even if you yourself have any clues
about the criminal’s identity, please
keep them to yourself.

Your clues or theories may deprive
others of the fun of discovering the
story for themselves. Besides...

The truth you find...
          ...may not be the real truth.

Rise Battle Text

Rise Kujikawa doesn't actually join the party member as a fighter, but within the code for requests for All-Out Attacks and Follow-Up Attacks, Rise has messages as well. However, they aren't actual lines, but instead developer messages informing testers that these should be impossible to see.

All-Out Attack:

You should never see this line!
If you're reading this, someone screwed up!
This isn't supposed to exist in the game!

Follow-Up Attack:

Dummy line!
This shouldn't happen!
Report this line if you see it, tester!

Unused Dreams

Apparently, at one point, dreams were meant to randomly boost Persona's stats instead of boosting Social Link status.

You had a dream about fighting...Your Persona's Strength increased by 1.
You had a dream mystical dream...Your Persona's Magic increased by 1.
You had a dream about hardship...Your Persona's Endurance increased by 1.
You had a dream about being chased...Your Persona's Agility increased by 1.
You had a dream about fate...Your Persona's Luck increased by 1.

Shuffle Time Arcana Failures

Some of the Arcana card effects during Shuffle Time can fail, such as the Magician not being able to change skills. However, there are such messages for all the Major Arcana cards, even the ones that can't fail. The ones that can't fail have these developer lines, some of which are quite humorous:

I pity The Fool when this message
appears, because it's a bug. Get
cracking, QA, and write it up.

This is a bug. The Priestess has
failed.

Please write this bug up,
  O noble QA tester.

Social Link Descriptions

In the final game, only two Social Links can be Reversed (Naoto's and Ai's) and only one can be Broken (Ai's). However, there are strings for the Social Link status screen for every S-Link in a Reversed and Broken state. Some imply that the girlfriend mechanics from Persona 3 had not been removed until later in game development, while others are messages stating that those messages shouldn't be seen.

This SLink should never reverse. If you see this, it's a bug.
