I needed an ME Region 8.0.4.1441 for a mac mini a1347 emc 2570.
I couldnt find a version close to the one I needed (8.0.4.1441) at ´╗┐https://www.win-raid.com/t596f39-Intel-Management-Engine-Drivers-Firmware-amp-System-Tools.html so I tried extracting from the Apple firmware.

Apple Firmware updates can be found here
support.apple.com/en-us/HT201518
you can extarct the pkg using
pkgutil --expand Mac2015002EFIUpdate.pkg efiupdate/
and then inside are the firmware updates
/Mac2015002EFIUpdate.pkg/Scripts/Tools/EFIPayloads

I was looking for a ME region for a Mac Mini, so I used
MM61_0106_B0A_LOCKED.scap

Opened it in UEFITool
github.com/LongSoft/UEFITool
There is a section called "MeRegionUpdateVolume" in EfiUpdateDataFileGuid
Its compressed but by opening it up to the leaf level you can access the uncompressed "Raw Section" , right click and extract body to a file.
This looks like the best match I could find for a fresh ME Region for my mac mini.

Is this a good / bad way to get a fresh ME region?

Attached is the extracted ME Region
