This was never really an issue until all these "new" Ultima.dll files started being included, lots of older scripts depend on older dlls, and trying to switch them over to new dlls doesn't usually work. So, now I need to merge two dll files, but I have to see what's different between the two first (something like WinMerge). I've done some initial Google searching, but I haven't run across anything that handles the first issue (comparing the two dll files), just how to edit a dll. Some folks said to use VS...well I've got that (VS 2015), but "use VS" isn't very descriptive. Anyone care to jump in here and help me accomplish this task? Your help is greatly appreciated!
