This is a guide for modding the files in Fairy Fencer F. Unlike the Hyperdimension Neptunia games on PC, Fairy Fencer F is much more open in regards to modding.

Before you read any further, it is a good idea to make a backup of your WHOLE Fairy Fencer F game just in case anything goes wrong.

This is also the first guide I've created, so sorry if there are errors!

Right now, you can easily edit the music, graphics, movies, and (most) sounds. Models are technically editable, however they require knowledge of hex editing. I'm in no way a programmer so if you wish to edit the model textures or models, you'll have to either manually hex edit it or find someone to make a program to edit them. Model swapping is of course possible.

Graphics editing:
Some sort of Image editing software that can open and export DDS files. I use Photoshop with Nvidia's Photoshop tools[developer.nvidia.com], but GIMP will probably work as well.

Model/Texture editing:
A Hex editor
Image editing software with the ability to export and import dds files (look above)

Audio editing:
Your favorite audio editing software, I recommend Audacity[audacityteam.org].

Video editing:
Any video editor that can export wmv, I use Vegas, but Windows movie maker will work (not recommended)

Graphics editing is quite simple.

As an example, I will edit Fang's art found in the menu. His portrait is located in /system/global/body/001.dds.

Simple import the image into photoshop or gimp and it should load fine. Make your edits.



Here is my edited graphic. Now it's time to export.

Since my graphic has an alpha map, we will need to export it with DXT3 compression, and NO mip maps. This is important, as the game will crash if you create mip maps.

How do i know if my texture has an alpha? In photoshop, go to the channels tab and you will see a layer named "Alpha 1".



If you are exporting an image that has an alpha, make sure that "Alpha Channels" are ticked when you save. Otherwise the alphas will not save even if you save it with DXT3 compression.



When this window comes up, change the setting to either DXT1 or DXT3. In my case, I will be using DXT3.



If you are in-game, restart for the changes to take effect.



I know, it's bad, but it was only made to show you it works.

Audio editing is also quite simple, however, not complete. I haven't figured out a way to get oggs to loop correctly.

The in-game battle music will automatically loop itself if you are giving the game input. If you aren't giving the game input, the game will not loop it.

If you are using Audacity, open it up and import the song you want to convert to ogg.

After you have imported your song, go to File -> Export and select ogg in the dropdown box.

At the time of writing this, I haven't completed the game, so my list of oggs may not be accurate to what happens in game. Let me know and I'll fix the names.
Here is the list of what each ogg is:

001.ogg - Title
002.ogg - Normal Battle
003.ogg - Second Battle
004.ogg - Tough Battle
005.ogg - Red Dawn (Don't know where it is in game, haven't played enough to know)

045.ogg - Event music/シャルマンのテーマ
046.ogg - Event music (?) / 暗躍する影の者たち
047.ogg - Event Music/ザ•チップチュン/Shenanigans
048.ogg - Event music/ Lola
049.ogg - Shalman's Piano~Air on the G String~
050.ogg - Mariano's Harp~Air on the G String~

Sound effects can be found in Sound/ JINGLE , VOICE, and VOICE_EN. For system sounds, they are in system/sound/se/SystemSE.acb. The file contains all of the oggs uncompressed, so you can easily find them with a hex editor and manually copy them out.
They are even listed in the order they are packed, so it's not too difficult.

Model and texture editing is quite interesting.

Characters are found in:

Game\Model\CHARA\

Each number refers to a perticular character. For example, Fang is 001, Tiara is 011 - 012, and so on. If a character has multiple costumes, they will be the next value up. So for Tiara:

011 = Normal Outfit
012 = Bikini

This can be said for every character.

In the character's folder, there are three folders and two files in it.

MOTION - Animations for said character
SOUND - Sounds the character makes when walking in the overworld. Same exact format as the System sounds .acb, with the oggs being completely uncompressed and easily extractable.
TEXTURE - Texture/Model
002.ism2 - Not sure what this is exactly, since it has development paths inside the file referring to textures
face.anm - The settings and positioning for the character's eyes, mouth, etc

Inside the TEXTURE folder is the cl3 model file.

This is the interesting bit, despite the fact that the 001 folder has dds textures, these are NOT used. The textures that are being used for a model is in the .cl3 model file. There are DXT1 compressed dds files inside the model, and if you're good at hex editing, you can swap the textures. Just make sure it doesn't overflow onto the next texture, or you will have the issue I had:


If you want to swap a model with another, you can do so, just make sure to not do so while the game is running, or else it will crash.

Video editing is also quite simple. The game seems to accept any sort of wmv I give it, so go nuts.

As you can see, there's a lot that could be done to fully make Fairy Fencer F moddable. There are several formats I've looked at such as scripts, but they all seem similarly packed to the models, and I'm not a programmer (yet) so I don't know any of that stuff. I'm also actively researching the files and I'll update this guide if I find anything worth noting.

If anyone wants It, i made wmv files that will are blank so there is no intro. You can get that here:
No Movie Mod[puu.sh] Just place the stuff inside "Movie" into your "Movie" folder inside your Fairy Fencer F directory. Make a backup first!

I'm also working on an HD mod that makes all of the HUD/Graphics up-scaled, since some of the graphics in this game desperately need it.

If I made any errors please let me know!
