  2. Open sun.ini.
  3. Go to the [Video] section.
  4. Change ScreenWidth and ScreenHeight strings to resolution of your choice.
Set values in configuration file, method 2
Another way to change resolution is to add this line beneath the [Video] lines in sun.ini:
This will let you change the resolution in the game menu to any supported by your computer.
"Widescreen in multiplayer works as described above. However, many hosts enforce resolution limits. If you try to join a game with a resolution limit, you will be forced to play the game at a non-widescreen resolution (usually 640x480). If you host a game and are using a widescreen resolution, you will not have the option of enforcing a resolution limit."[3]


The game can only run in windowed mode if it is run in 16-bit color mode or has a fan-made renderer that bypasses this requirement.

  6. On the Libraries tab, add "wsock32.dll" for the library replacements.
  7. Add the following tricks (from WineHQ):

  9. Right-click on that key and create a new key game.exe
