Upgrade from v3.x or Older

Get Ready

Version 4 is the biggest update to P3F CEP yet, so there are some additional steps to the upgrade process. We've written out a full set of upgrade instructions this time to make everything as clear as possible.

Make sure to read the directions entirely. Rushing these steps will result in nothing but frustration.

Upgrade P3F Mods Folder

Rename Old P3F Mods Folder

Your PS2 BIOS, P3F ISO, and save data are all in your old P3F Mods folder.

Instead of deleting your old folder right away, we'll rename it for now so you can copy over your game files and save data later.

• Rename your old P3F Mods folder to P3F Mods OLD.

Get New P3F CEP

• Download the latest version of P3F CEP now if you haven't already.

• Unzip your downloaded P3F CEP archive and locate the P3F Mods folder inside.

• Move the P3F Mods folder to the same location as your P3F Mods OLD folder.

Install Prerequisites

• In a new window, open your new P3F Mods folder, then open the Setup folder.

• Update to the latest prerequisites, either by running .Install_Prerequisites.exe in the P3F Mods\Setup folder or by manually installing them.

Copy Old Files

P3F CEP v4 has a brand-new tool called P3F CEP-o-matic that makes upgrading easy! CEP-o-matic will handle putting everything into its proper place in your P3F Mods folder.

• Open your P3F Mods OLD\.PCSX2 folder.

• Copy the following files into your new P3F Mods\Setup folder:

Once everything is copied over, your P3F Mods\Setup folder should look like this:

Run CEP-o-matic

• Make sure you have everything listed above in your P3F Mods\Setup folder, then launch .Prepare_Files.exe to start CEP-o-matic.

CEP-o-matic will automatically do the following:

• Locate your game ISO, verify it is a valid P3F disc image, and rename it to P3F.iso

• Extract the SLUS_216.21.elf executable needed to emulate P3F with mods

• Locate your PS2 BIOS, either as a packaged BIN file or as a collection of loose files

• Locate your PS2 virtual memory cards (save data) Mcd001.ps2 and Mcd002.ps2

• Move everything into its correct location in the P3F Mods\Files folder

You don't need to do anything. CEP-o-matic will do all the work for you!

• Once the All finished! message appears, press Enter to close the program.

Test Run PCSX2

Before we continue, let's make sure that the new version of PCSX2 can launch P3F and that your save data was copied over properly.

Launch P3F

• Open your P3F Mods folder and launch either:

  • Launch P3F Windowed.bat or

  • Launch P3F Fullscreen.bat

• PCSX2 will open and launch Persona 3 FES. Remember, no mods have been installed yet!

Test P3F

• Make sure PCSX2 launches the game, plays the opening cutscene, and shows the title screen.

• Select Load Game in the main menu.

  • Make sure your save data appears and that you can load it into the game.

Moving On

• Close PCSX2 completely once you're ready to move on.

  • To exit fullscreen mode, double-click the game window.

• If you have any important files in your P3F Mods OLD\Backups or P3F Mods OLD\Notes folders, copy them into your new P3F Mods folder now.

• Once you are sure your save data is working in the new PCSX2 and any important files have been copied over, you can delete your P3F Mods OLD folder.

Upgrade Aemulus Folder

Upgrade Packages

Delete Existing P3F Packages

• Open your old Aemulus folder.

• Open the Packages folder and delete the Persona 3 FES folder inside.

Import P3F CEP Packages

• In a separate window, open the new P3F CEP archive you unzipped and locate the Aemulus\Packages\Persona 3 FES folder inside.

• Move the Persona 3 FES folder from the archive's Packages folder to your Aemulus folder's Packages folder.

Upgrade Config

Delete Existing P3F Configs

• Go back to the base Aemulus directory.

• Open the Config folder and delete the Persona 3 FES folder inside.

Import P3F CEP Config

• In a separate window, open the new P3F CEP archive you unzipped and locate the Aemulus\Config\Persona 3 FES folder inside.

• Move the Persona 3 FES folder from the archive's Config folder to your Aemulus folder's Config folder.

Update Aemulus

• 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 6.4.3 or higher.

Configure Aemulus

Some settings in Aemulus need to be configured for the new PCSX2.

Set Game to Persona 3 FES

• Make sure the game is set to Persona 3 FES and the loadout is set to P3F CEP.

Set File Paths

The file paths for P3F CEP 4.x are very different than those in previous versions, so you'll need to set them up again.

• Open the P3F ⚙️ Config window.

• Click Browse to the right of each box and change the file / folder paths to the following:

• When you are done, close the Config window to return to the package grid.

Continue Setup

You're not quite done yet!
