waltc: Don't know about that, but suggest you try them to find out. You can simplify things for yourself by copying and pasting your TWII directory back to the drive on which it is currently installed, as it will copy back with "--copy" automatically affixed to the current directory name, so that it won't be accessed. Use your original install directory to experiment with, and if the install gets messed up you can delete the original install directory and remove "--copy" from the directory name, and you are back in business with a pristine copy without having to reinstall the game. (I always do this with large games that take awhile to install when I want to experiment with mods.)
BTW, what mod is that...? Looks interesting--have a link? I know that the game engine settings I used for TWII work fine with 2.03 installed.
