qzdoom/src/win32/i_system.cpp
Randy Heit b132575533 - Added a dialog that gives the user the chance to fix things if the config 
could not be saved for some reason.
- Added the writeini console command to write the config file, optionally
  specifying a specific file name for it.
- Fixed: "Multiplayer" demos that only had one player were not played back
  properly because the demo playback code only checked the number of players
  to determine if it should be played as a netdemo.
