If you’re looking to add a few Sims 4 Foundation Sims to your Xbox One gaming experience, there are a few ways to do it. The first is to use the console’s built-in emulator, which can be found in the “Xbox” section of the “Settings” menu. Once you’ve set up your emulator, open it and select “Sims 4 Foundation.” Once you’ve added the Sims 4 Foundation Sims, they’ll be available for play as soon as they’re added to your game. The second way is to download and install the game’s “Add-ons” folder. This folder contains a variety of files that can be used to add additional content to your Xbox One gaming experience. The most common file in this folder is “Add-ons_xboxone.exe,” which allows you to add new characters, objects, and locations into your game. If you want more control over how these files are used, you can create an XML file that describes how these files should be used. This file can be found in the “Add-ons” folder and is called “Sims4_foundation_xboxone.xml.” Once you’ve created this file, you can use it as a guide for adding new Sims 4 Foundation Sims into your game.
