Looks like anything needed is already in CCom12.
fc /B orig.file modified.file > diff.file
where:
orig.file = "Complete_CCoM_12_0\MODS\CCoM_CaptainsChoiceOfMods _Release_120_BASIS_EC\sh3.exe"
modified.file = "Complete_CCoM_12_0\MODS\Ahnenerbe_WS-GUI_1920x1080_for_CCoM_by Wurmonkel\sh3.exe"
example:
fc /B sh3.exe sh3_WS.exe >test-sh3.txt
Result: (only related for exactly these exes!)
