1. The mod to disable Easy Anti Cheat aka EAC
   
2. Mods that you want to install

All mods I've found that work are on videogamemods. Do be aware the mods by Zekken are all paid through Patreon for the most part.

Start by changing to desktop mode (done by hitting the steam button, press power, and then go down and select switch to desktop). Bring up dolphin, and navigate to wherever you have the game installed whichever place will have steamapps>common>JUMP FORCE. For all mods you'll want to create a folder in steamapps>common>JUMP FORCE>JUMP_FORCE>Content>Paks make a folder called ~mods and put all mod files in there.

All mods should be extracted into their own folders based on what the file is: for example adding the mod that changes a character's model is put in a folder so the files won't override each other. For example if you wanted to have a cell dub mod you'd put the files for it in a folder named ~Cell Dub Mod.

Now in order to load the game without anti cheat and so mods can be used; now mind you can't go online for matches but I believe online is shutdown anyway, and its a bit of a set up. You must be in desktop mode for this

    
1. Download the mod Disable EAC from Mastaklo
       
2. Unzip the folder and move the exe to steamapps>common>Jump Force
       
3. Overwrite the exe with the one from the mod
   
4. Bring up the steam launcher while in desktop mode
   
5. Go to add a game and select add a non steam game
   
6. Browse and navigate to the folder for Jump Force and select the Jump Force exe
   
7. Add selected programs
   
8. Run the Jump_Force exe at least once or twice to get the game to run

After running the modified exe at least once you should be able to launch the game from the Jump Force entry itself.
