Widescreen Mod v3.01 fails to install on a clean install of TotSC 1.3.5521 from 3 CD set, however, it succeeds after installing the "Intl" 5521 patch. This particular requirement isn't mentioned in the README.
This is the most useful thing I have read on this forum for the in the past 3 hours. Version 3.04 of the Widescreen Mod doesn't work on the native 5521 3 disc install either. I have yet to find the International Patch, but this would be key information for the README or one of the sticky posts. It sure would save time surfing through the epic rudeness from the moderator.
