Modding Persona 3 Reload on the Steam Deck

Guide on how to get mods for Persona 3 Reload working on the Steam Deck using Reloaded II and Protontricks.

Introduction

This Steam guide covers the ASI Loader method to modding P3 Reload, you may prefer this guide[gamebanana.com] by rudiger__gb[gamebanana.com] which uses a completely different method.

Protontricks Setup

You will need Protontricks, if you already have that installed you can skip this entire section after reading this.

Open up Discover and search for Protontricks then install it.

After that, search for Flatseal then install and open it.

Click on Protontricks on the left, scroll down to Filesystem then click All user files and give permission to /run/media under Other files.

Open Protontricks
Find & click Persona 3 Reload in the list, then click OK

A Winetricks window will eventually pop up, click Select the default wineprefix, then OK

In the new window click Run winecfg, then OK

In the Wine configuration window, click the Drives tab, then check Show dot files (towards the bottom left)

Click Apply then OK, and close any other Winetricks windows.

What is Flatseal and what exactly am I giving access to?
Flatseal allows you to review and modify permissions from your Flatpak applications, we are giving Protontricks access to any external drive (like a MicroSD card) you may have in case the game is installed there.

Reloaded II Prerequisites

Before starting, run Persona 3 Reload at least once with Proton 8.0-5 (or your preferred Proton) to generate the prefix.

Next download these:
Visual C++ 2015-2022 Redistributable (x64)[aka.ms]
Visual C++ 2015-2022 Redistributable (x86)[aka.ms]

.NET 7 Desktop Runtime (Install BOTH x64 and x86)[dotnet.microsoft.com]
.NET 8 Desktop Runtime (Install BOTH x64 and x86)[dotnet.microsoft.com]



Download each one by right-clicking > Open With > Protontricks Launcher.
After it opens, scroll down and click on Persona 3 Reload's Prefix.



Do this one at a time with all 6 files.

Reloaded II Setup

Download Reloaded II[github.com] and extract it to a folder anywhere you want, the name also doesn't matter.
(I created a folder called P3R Reloaded II and put it in my P3R Directory).

Open Reloaded II the same way you downloaded the prerequisites, you will need to open it like this every time. Make sure you are opening Reloaded-II.exe and NOT Reloaded-II32.exe.


Click Add an Application and direct it to your P3R.exe

Location will vary depending on where the game is installed, double check it's correct.

Click on Advanced Tools & Options, toggle Auto-Inject on, and Deploy the ASI Loader.

Go to your Steam Launch Settings for Persona 3 Reload and add WINEDLLOVERRIDES="DSOUND=n,b" %command%

Now we'll need to download our first mod, Persona 3 Reload Essentials[gamebanana.com]. There are 2 ways to install mods, automatically and manually. Pick whichever method you prefer.

Installing Mods Manually

Whenever you download a mod, make sure to also download any requirements it may have.

Wherever your Reloaded-II.exe is located, there should be a folder named Mods. You'll want to create a folder for each mod you download in there.

Each Mod in its folder should look something like this.

This 2nd mod, Is It Working?[gamebanana.com], isn't needed but will tell you if mods are working on the title screen, which makes testing much faster.

Installing Mods Automatically

Whenever you download a mod, make sure to also download any requirements it may have.

In Reloaded II, click the top left button to browse P3R mods on GameBanana. Simply clicking a mod and clicking download will download it.

This 2nd mod, Is It Working?[gamebanana.com], isn't needed but will tell you if mods are working on the title screen, which makes testing much faster.

Managing Mods

Make sure Persona 3 Reload Essentials is always at the very top.

Some mods have extra settings that you can toggle or customize by clicking Configure Mod, some others will have some kind of text file you can use instead.

Final Notes

You should be good to go assuming you didn't misstep along the way. If you have any questions or need help, try asking in the Persona Modding Discord[discord.gg]. If you don't have Discord or just lack a phone number (me) you can try posting a question on GameBanana[gamebanana.com] but it may take a long time to get any responses. Please keep in mind that, at the time of writing this, Persona 3 Reload's Modding is still in its infancy and will likely develop a lot over the next year.

Hope this helped!

every time i try to open reload-II it opens a download for net .9.0 (which i dont even have installed so i dont know how it just opens that) and instantly closes

[riceman]

protontricks launcher isnt available to launch with the reloaded 2 it wont show up

Tried opening Reload via ProtonTricks and all I get is an error message

[Captain Diagram]

Sorry for super late response, didn't have enough room to install Persona 3 or 5 until now. I only encountered that issue when using Proton versions that weren't Proton 8.0-5, 8.0-5 fixed it for me.

Hello! Thanks for making this guide. I've been having issues in opening reloaded II on my steam deck. I've gone through all of the instructions twice but when opening Reloaded II via winetricks it usually just opens a blank Reloaded II before crashing and becoming unable to close or to do anything with. Any idea on what I'm doing wrong or any possible fixes?

[Captain Diagram]

On the top of my head it's probably related to what version of Proton you have selected for P3R in Steam. Not sure tho and don't currently have P3R installed to test, if changing proton versions doesn't do anything try reinstalling protontricks.

You can also try installing them by opening Protontricks > Clicking on Persona 3 Reload > Select the default wineprefix > Install a Windows DLL or component > checking MS .NET Desktop Runtime 7.0 LTS and vcrun2022 > then clicking OK. I haven't used this method in awhile but it should still work.

These are pretty much all my ideas, if your still having a problem I'm not educated enough to help lmao somebody online probably has encountered whatever issue you'll run into.

Hello! The dotnet.exe files are not opening through Protontricks. The popup for Proton comes up, but selecting Persona doesn't end up doing anything.

[CherriCola]

Reloaded runs awful on deck, it just crashes for literally anything😭

[devonmorris190]

i was able to download the .net things fine but when i tried downloading the vc++ i got an error message saying it couldnt work on anything besides windows 7 or above
