Downgrading to Version 1.23.00 on Linux Mint

Before you begin, right click your copy of DBXV2 in your Steam Library, click on Properties, then go to the Updates tab & set the game to only update when you launch the game. Make sure that you've already downloaded Dragon Ball Xenoverse 2 from Steam. Delete every folder & file from inside your DB Xenoverse 2 Folder by right clicking the game in your library, hover over Manage, then click on Browse Local Files. Everything you see in that folder should be deleted.

Step 1: Download "DepotDownloader-linux-x64.zip" from this Github here: https://github.com/SteamRE/DepotDownloader/releases
Step 2: Extract this zip file anywhere.
Step 3: In the same folder where the extracted files are, right click inside an empty space inside the folder & open Terminal.
Step 4: Copy & paste the following into the Teminal window, but the only thing that needs to change is the text that says YOURUSERNAME. Switch that to your Account username. Not your Profile username that's shown to everyone, your Account username.

./DepotDownloader -app 454650 -depot 454651 -manifest 5522356754303651877 -username YOURUSERNAME -remember-password

Step 5: Hit the enter key.
Step 6: Once the download finishes, copy every file from inside this folder. Downloads/DepotDownloader-linux-x64/depots/454651/NUMBERS
Keep in mind that there is no "NUMBERS" folder, that will actually be a random string of numbers for you.

Keep these files somewhere where they won't be lost, that way you can always keep your mods for version 1.23.00. If you want any other version of DBXV2, there are other Steam guides that cover how to do just that! This guide is just for the current latest version of XV2 that you could mod before the mods stopped working.

CONGRATS! You can now keep Xenoverse 2 modded forever!
