There are a couple things that might help:
Something like FreeFileSync (https://freefilesync.org/) will allow you to compare the Program/Resource files with a "binary" comparison so you can limit investigation for things that are truly a difference and ignore things that are unchanged.
For the changed/different Program or other text files, use a visual file diff tool to quickly find the differences.
Thank you Jeffrey, you are the man! I have updated the Resources folder (including INI folder) and no bugs syntax errors so far. Errors start to occur when updating PROGRAM folder, but I can see that 80% of the files can be updated, the other ones cannot because of the updated engine (at least that seems logical). I might have something in a couple of days. Then I can start fixing the aesthetic issues mostly related to position of some icons in sailing and world map mode. If I succeed, I will start promoting maelstrom engine on Youtube, because like it or not, New Horizons is still the most popular mod for Storm engine games. That should be used to boost the sale of Maelstrom engine and hopefully make all this amazing work that you do payable.
