由国外网友制作的一款FIFA21补丁导入工具，这是第四个版本v1.0.6，5月1日更新，主要针对FIFA21的补丁添加工具。
里面有两个工具一个是编辑工具FIFA Editor Tool 1.0.6（主要提供给喜欢DIY的玩家编辑和制作MOD用），一个是MOD补丁添加工具FIFA Mod Manager 1.0.6（打补丁必须用到的工具）
v1.0.5.5更新日志：
v1.0.6更新日志：
- Batch exporting of DDS legacy assets now supports conversion to PNG, TGA, and HDR
- Made a small optimisation to avoid a memory copy when reading resource data
- Updated various third-party dependencies
- Added support for importing and exporting of MovieTexture2Asset files from the right-click context menu of the data explorer
- Added support for importing from, and exporting to, MP4, AVI, and MKV containers with various video and audio codecs when importing or exporting MovieTexture2Asset files
- An open texture editor will now refresh the displayed texture, if the texture is imported from the right-click context menu of the data explorer
- A custom icon is now shown for TrueTypeFontAsset files on the data explorer asset list, instead of the generic icon
- Tab headers should now update more reliably (displaying the * when the asset being edited is modified)
- Added importing and exporting support for AtlasTextureAsset files, as well as a visual editor to view them
- Bug fix for the BIG editor not opening when Windows is using a Turkish locale
- Added support for importing and exporting LuaRunnerCompiledLua assets
- The Toggle Texture setting is now maintained after importing a mesh in the mesh editor
- Bug fix for an error when importing a mesh in the mesh editor, while displaying a LOD other than the first
- Added support for importing and exporting RimeTtfAsset files as .TTF- Added a legacy PNG viewer
- Added support for PNG images in the thumbnail view of the legacy data explorer
- PNG legacy files now have the same icon on the data explorer as DDS files
- RimeTtfAsset files now have the same icon on the data explorer as TrueTypeFontAsset files
- Legacy TTF files now have the same icon on the data explorer as TrueTypeFontAsset and RimeTtfAsset files
- Added a slider to the data explorer thumbnail view, to adjust the size of the thumbnails
- Added additional error logging when the mesh editor fails to load a mesh
- Minor optimisation when updating the data explorer folder list
- Updated the SDK
- Exporting of more than one EBX asset from the file list now supports more asset types (LuaRunnerCompiledLua, TrueTypeFontAsset, RimeTtfAsset, MovieTexture2Asset, subtypes of TextureAsset, AtlasTextureAsset)
- Added support for batch exporting of EBX assets from the right-click context menu of the folder list, which exports files within subfolders too. This has the choice of exporting all assets, or only those that have been modified in the current project
- Improved the progress reporting and cancellation when batch exporting from the file list
- Reverting an asset that has been modified will now mark the project as dirty, and closing the editor or trying to create a new project will prompt you to save your changes
- The legacy texture editor for DDS files now refreshes after import to show the new image
- The corresponding asset entry in the legacy data explorer is refreshed to apply the current filters, after importing a DDS file
- A message is now shown on startup if a new SDK has been created, but cannot be used because another instance of the editor is still running. This also avoids the SDK being created a second time unnecessarily
- Added a setting on the mesh viewer to switch between a light or dark background. The default value can be altered using a new application setting accessible from File -> Settings
- Updated the error message shown when the game fails to launch, to include the error type and message
- Extra logging when the mods have changed and need to be reinstalled, or when they haven't changed and the game can launch immediately
- Bug fix for an issue where only one archive can be installed, and further attempts to install archives will fail
- The overlay shown when launching the game is now split into two parts: the first part is shown when mods are being applied to the game, and the second is shown afterwards, when the game is being started
- Changes to the applied list are now saved automatically every minute, in addition to when the program is closed
