BUG ModManager V4.0 is a Mod Manager made with AI assistance from Gemini and Claude. It was developed and tested for FS25, and it should work with all Farming Simulator games that use this structure.
Behind the scenes, it works with the storeData data in modDesc.xml and the XML files inside the storeItems folder.
Features
- First, pick the folder containing your MODs from the left menu.
- Choose “Load Files”, then wait for the files to show up. After the mods are listed, you will get a warning. Click “OK” and keep going.
- Every mod comes with ACTIVE and EDIT options. ACTIVE tells you the current status.
- Press ACTIVE once to DISABLE the mod. Its ZIP extension changes to
.zip_BAK. You can still see the mod in Mod Manager, but it is disabled in the game. - Close and open the program again to see disabled mods and reactivate them.
- EDIT lets you see the XML files in
storeItemsinsidemodDesc.xml. Those files are the mod’s in-game store items. - You can change the Name, Brand, Lifespan, Price, and Power status of store items.
- As soon as you edit one of these fields, SAVE becomes active. Press SAVE to change the matching field in the mod.
- There are no controls on the input fields. A special character or letter entered where a number is needed can make the game ignore the value or break the mod.
- ACTIVE turns the relevant storeItem field in the
storeItemssection ofmodDesc.xmlinto a comment line in the code. The game store cannot see or display that file anymore, and the original state can be brought back. - Mods with multiple store items let you remove items one at a time. So, when a mod has a tractor and a trailer, you can remove either the tractor or the trailer from the store.
- Remember to use SAVE after each operation in the EDIT window.
- EDIT is active when the
storeItemssection is inmodDesc.xml. Without that section, this code is deactivated. - Two languages are included. The top right menu lets you switch the default language to Turkish or English.

Version 3.3.5.0 changes:
- ModHub now includes a “Non Installed Mods” filter. It only shows mods that are not installed.
- The main menu has a filter for showing only mods with added notes.
- Performance and Speed Optimizations (Freezing Issues Fixed): Heavy disk operations such as saving, backing up, opening/compressing ZIP files, and editing details of large mod files will no longer cause the application screen to drop to “Unresponsive”. Additionally, the mouse cursor will show the waiting status.
- Most crashes caused by unexpected errors have been prevented. The application will no longer crash completely when searching on ModHub, switching between categories, pressing the refresh button, or when the internet connection is lost. In such cases, the application will continue to work safely and will show the error in the status bar or in an alert box.
