To install a patch: Download it. Run WinZip to extract the files. Exract the files into
your c:\Unreal\System directory, replacing the existing versions of the files. If you've
installed Unreal into a directory other than c:\Unreal, then extract the files into the
System subdirectory off of your custom Unreal directory.
The first time you run the upgraded version of Unreal, you may be asked to put your
Unreal CD in the drive. This step is required because files must be loaded off the CD
during the patching process. Make sure you have your original Unreal retail CD handy
before installing the patch.
After installing the 220 patch, you will need to reconfigure your Unreal settings such
as your keyboard configuration, 3D hardware, and resolution. However, your savegames will
not be lost; savegames from previous versions will work properly.
Warning: Patches designated as "Public Betas" have not undergone rigorous
internal testing and are for enthusiasts who are comfortable using experimental software.
After the patches have settled down into a stable new version, an official (non-beta)
release will be made.
