the default, unmodified GOG install is compatible, just install the hdmod (0.8.6) as instructed. to uninstall, delete the hdmod folder.
if you have TFixed your install, make sure you have used the latest version (1.18a at this moment), and install the hdmod (0.8.6) as instructed. if you want to uninstall, just run TFix again, select the mods you want, repatch, and delete the hdmod folder when done.
