To unzip the files you download, you can use Winzip,
the Info-Zip unzip program,
PKZIP or any other program that knows how to handle zip files.
Note that TTDPatch does not change any of TTD's files.
You can write-protect the TTD executable to be sure.
Instead, it will copy the old executable (either ttdx.exe,
tycoon.exe or gamegfx.exe)
to ttdload(W).ovl, and modify this copy only.
You can switch between TTDPatch and the regular TTD at any time, simply by
choosing which program you run. ttdpatch(W).exe is for running with the
patch, and the regular ttdx.exe, tycoon.exe or gamegfx.exe
for when you want the original TTD.
However, savegames that are saved while certain switches are activated may be incompatible with versions not running this patch. This also applies to scenarios created with the scenario editor. Incompatible savegames may cause TTD to crash, so be careful when loading games saved with the patch into TTD.
