I think a majority would fail miserably if they were provided only the code changes.. AND, the mod author has no way of knowing what other changes you may have already made for other add-ons.. If this is what you're used to with OSC, then that explains a LOT of the problems I saw with mods when last I peeked in there..
Yes.. get Winmerge (or a similar tool) and try 1st before giving up..
as for OSC??? IMO staying with OSC is a step backwards.. That project is NOT moving forward at all..
