Simple GUI or alternatively command-line program with a bunch of .bat files to make modifications to the XWing Alliance binary, in particular those often necessary to allow it to work on modern systems.
Changing game resolution, maximum frame rate and enabling 32 bpp rendering (hack, breaks some things like load screen) so that anti-aliasing can be used are also possible.
Basic fixes for graphics issues in hardware 3D mode are available for XWing95, TIE95, X-Wing vs. TIE Fighter and Balance of Power, too.
