This file, when unzipped to SMAC_Win2000_XP_Compatibility_Update_v1.03f.exe, should be used to update SMAC to version 5.0. It should be run on systems with all recent versions of Windows, not just Windows 2000 and Windows XP. In addition to making the game compatible with recent versions of Windows, the patch also makes the following (undocumented) changes to the game:
1. Allows Yang and Morgan to have Golden Age pop booms.
2. Fixes facility maintenance costs at higher difficulty levels.
3. Fixes problems with using the command DirectDraw=0 in Alpha Centauri.ini.
4. Removes the requirement to have the CD in the drive when playing.
