Step 4: Watch for Updates

After every official game patch, re-extract the strings. EA often leaves "string garbage" (unused keys) in place, which can be more revealing than the used ones.

8. Testing

1. Launch the game and navigate to the UI/object that uses your string.
2. Verify:
   • Correct text displayed.
   • Tokens replaced correctly (e.g., names, numbers).
   • No layout overflow (text too long).
3. Switch game language to test other language packages.
4. Check for console/log errors if strings fail to load (Sims 4 logs in Documents/Electronic Arts/The Sims 4/logs).

1. Tools you’ll need

• The Sims 4 game installed.
• S4PE (Sims 4 Package Editor) or Sims 4 Studio — for opening and editing .package files.
• A plain-text editor (Notepad++, VS Code) for writing XML/CSV or JSON where needed.
• Resource.cfg (usually not needed to edit) and a mod folder in Documents/Electronic Arts/The Sims 4/Mods.
• Optional: A translator/localization tool if you add multiple languages.
