Widescreen #2[citation needed]
Another way to change resolution is to add the line beneath the [Video] lines.
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]

OS X/Linux emulation[edit]

Setup Wine[citation needed]
  1. Download the game.
  2. Run the installer with Wine (right-click):
  3. Edit SUN.INI and choose whatever you want (resolution, etc.):
  4. Open winecfg.
  5. On the Applications tab, click on "Add Application", and point to the GAME.exe
  6. On the Libraries tab, add "wsock32.dll" for the library replacements.
  7. Add the following tricks (from WineHQ):
  8. Run 'wine regedit', browse to HKEY_CURRENT_USER\Software\Wine. If there is no key (the stuff with folder icons) called AppDefaults, then create it.
  9. Right-click on that key and create a new key game.exe
  10. Create a new subkey Direct3D. In that key create two string variables:
  • DirectDrawRenderer with value opengl
  • RenderTargetLockMode with value readtex
  • Run the game through Wine and enjoy.[4]
