Persona 4 is the fifth 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.

Unused Voice Clips There's a lot of them!

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

Unused Graphics A little less early stuff this time around.

Persona 3 Leftovers Stuff that was never seen on the Iwatodai school trip.

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 original 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.

Debug Mode

To do: Document this better and document which menus do and don't work in the US version, also document the hex numbers for the menu options in the japanese version to avoid the debug menu staying on screen. Also document what the debug options do.

In the Japanese release of the game, there exists a debug menu, the menu is a little broken since the menu gets stuck on screen and inoperable once you select an option but works otherwise. This was removed in the US release of the game, although you can still access some of the menu options. The menu options were also translated in the US version, but not the sub menus.

To access the menu in the Japanese version, use code 205F0AD4 00102D10, this will replace the game start sequence with the debug menu sequence. There are also some hidden debug menu options, which you can enable by setting the byte 4 lines below the debug menu option name from a 00 to a 01. (01 enables it, 00 turns it off). Doing this also lets you see that this debug menu has an otherwise unseen scrolling feature

In the US version this Debug menu was removed, though, you can still access the menu options with this code 205DD4D4 00xxxxxx (Also replaces game start sequence), some of these don't work in the US version

Replace xxxxxx with the corresponding hex numbers.

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 5 Stasis Giant enemies.

Unused Music

The "Burn My Dread -Reincarnation: Persona 3-" album version of "Deep Breath Deep Breath" is oddly not a Persona 3 leftover.

An unknown dummy loop found inside the files of the game.

Unused Videos

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.
• Teddie's character portrait is different.

Unused Personas

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: Check over things and document anything else noteworthy.

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 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.

There are six "Debug Personas", named DBG35, DBG45, DBG55, DBG65, DBG75, DBG85. 35 has all stats at 22, 45 has all stats at 28, 55 has all stats at 34, 65 has all stats at 40, 75 has all stats at 46, and 85 has all stats at 52. Their level is the same as their number.

There are also two unused Personas with untranslated names in the English version: Black Izanami (黒イザナミ, ID 0E0) is a level 1 Fool arcana with no resistances, 3 strength, 2 magic/endurance/luck, and 99 agility, with the default Izanagi moveset (Zio, Slash, and Rakukaja). It uses an invisible persona model and Ongyo-Ki's art. Ookami (大神, ID 0E1) has the skills Infinite endure and Myriad Truths (used in the Izanami fight), and it uses Izanagi-no-Okami's model and Ongyo-Ki's art.

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.

Unused Items

Oddities

• Every dungeon in the game has dummy floors up to the next ID multiple of 10, these are usually unnamed, however Yomotsu Hirasaka has paths 10-13 named, despite path 9 being the final floor.
• Usually unused floors contain no shadow data and only spawn default white shadows in side rooms, however some floors have shadow encounter data, like the last dummy floor of Yukiko's Castle (ID 019)
• The protagonist has a default name, being 主人　公 in the japanese version (translates to "Main Character"), you can't see this normally in-game, though. In the english version, it shows up as a square
• With the unused dummy personas, persona in the slot 0D0 is named as 0D1, this goes on with 0D1 being 0D2 until 0D3, where it's named 0D4 and 0D4 being also named 0D4
