It will save the preferences.I think @Phillipos could have worded this with more tact and politeness. As a feature request, would it be possible to have DaedalusX64 launch in 4:3 as the default aspect ratio? Like a user changeable setting in the preferences.ini? There were some in there like ViewportType, TVEnable, and TVType, but I'm not sure which or any of these control resolution or aspect ratio.
