Ok, I'm sorry to say that, but IMO Warzone2100 Portable (2.2.4 Rev 3) has a bad design:
- The Warzone2100 Portable launcher ignores the "ingame" screen resolution settings and those of the file "Data\settings\config". No matter what the user set within Warzone2100 or the config file, it won't be used. It always launchs Warzone with the commandline parameter "--resolution $SCREENWIDTHx$SCREENHEIGHT", which is 1024*768 by default.
- $SCREENWIDTH and $SCREENHEIGHT could be set by using the Warzone2100Portable.ini though, but the launcher looks for it within the Data directory. That's not documented and not the standard place for the ini file.
- As mentioned in another thread, Warzone Portable starts in fullscreen mode by default. That doesn't work on all systems, so the windowed mode should be the default
