We will use a dedicated directory for our P4G modding tools. If you ever need to create a file backup, take a screenshot, or write down a note, save it in this folder to stay organized.
Important Terms

  • Unzip your downloaded P4G CEP archive.
  • Open the unzipped archive and locate the P4G Mods folder inside.

What you do next depends on whether you already have a P4G Mods folder from a previous P4G CEP installation on your PC.
I don't have a P4G Mods folder
I already have a P4G Mods folder
  • Move the P4G Mods folder to a suitable location on your PC.
We recommend creating a new top-level directory such as C:\Mods.
  • In a new window, open your old P4G Mods folder that was already on your PC.
  • Copy just the .Reloaded II and Setup folders from the new P4G Mods folder to your old P4G Mods folder.
Double-check your folder path!
Make sure your P4G Mods folder is NOT in any of these locations:
  • OneDrive
  • Program Files / Program Files (x86)
  • The Downloads, Documents, or Desktop folders
  • The Music, Pictures, or Videos folders
  • Any Steam or Steam library folder
  • The Persona 4 Golden game folder
If your P4G Mods folder is in one of these locations, you must move it to a different location before continuing.

Aemulus Package Manager is a program that downloads, organizes, and builds mods for many different Persona games. It's included with P4G CEP!
Since you might want to use Aemulus for multiple Persona games, not just P4G, we'll place it alongside the P4G Mods folder instead of inside it.
Important Terms

  • In your unzipped P4G CEP archive, locate the Aemulus folder inside.

What you do next depends on whether you already have an Aemulus installation on your PC.
I don't have Aemulus
I already have Aemulus
  • Move the Aemulus folder to the same location as your P4G Mods folder.
These steps will delete all of your existing Aemulus packages and configs for Persona 4 Golden (PC), including packages that are not part of P4G CEP.
Packages for other Persona games will not be changed or deleted.
Make sure to back up anything you want to keep before starting!

  • In a new window, open your old Aemulus folder that was already on your PC.
  • Launch Aemulus.
  • If you get a prompt to update the program, select Yes.
  • Once Aemulus has downloaded the update, click OK to restart the program.
  • Once Aemulus restarts, confirm in the top-right corner of the window that the program is version 6.1.3 or higher.
  • Once you are done, close the Aemulus program.

  • Open your old Aemulus folder again.
  • Open the Packages folder and delete the Persona 4 Golden folder inside.

  • In a separate window, open the new P4G CEP archive you downloaded and unzipped and locate the Aemulus\Packages\Persona 4 Golden folder inside.
  • Move the Persona 4 Golden folder from the archive's Packages folder to your Aemulus folder's Packages folder.

  • Go back to the base Aemulus directory.
  • Open the Config folder and delete the Persona 4 Golden folder inside.
There might be folders for other Persona games here as well.
Do not delete Config.xml.

  • In a separate window, open the new P4G CEP archive you downloaded and unzipped and locate the Aemulus\Config\Persona 4 Golden folder inside.
  • Move the Persona 4 Golden folder from the archive's Config folder to your Aemulus folder's Config folder.
Do not copy or move Config.xml.

Do not skip this step, even if you've already done this before!
The prerequisite installer regularly gets updated with the latest runtimes that contain performance and security fixes.
There are seven core runtime libraries that our modding tools require to run.
You can install them automatically or manually.
Important Terms

P4G CEP includes the All-in-One Prerequisite Installer program (source), which will automatically download all of the prerequisites and run the installers one at a time.
  • Open your P4G Mods\Setup folder.
Yes, the license is bigger than the program.
  • Run Install_Prerequisites.exe. A console window should appear.
  • Follow the instructions in the console window to install each missing prerequisite.

Alternatively, you can manually download and install the prerequisites yourself.
