The patch contains various bugfixes and game improvements such as widescreen support, and provides some GUI tweaks. It also enables the use of the FMSel fan mission loader frontend with Thief 3 and bundles the most important T3 mods. It works with the GOG and Steam versions of the game.
Unofficial patch for Thief 3: Bugfixes, widescreen support, GUI tweaks, FM loading. Much smaller download for when there's no changes to the bundled mods from the previous version.
New in 1.1.10 Update Edition:
After first-time installation the game should start in the current desktop resolution.
The installer will set up a start menu group with shortcuts to the readmes, the options folder, installed FMs folder etc. By default it will also create three icons on your desktop: A yellow glyph icon for the original game, a cyan version for the fan mission selector and a green version for the SneakyTweaker tool.
The patch has its own configuration file, SneakyOptions.ini. Normally this should be changed only through the tweak tool, but for advanced options manual editing is necessary. In that case it can be found through the Sneaky Upgrade start menu group (in Local Folders).
Beginner's quick start guide to playing FMs using the FMSel loader frontend: (To play using GL, just make sure GL is installed before installing the Sneaky Upgrade.)
The patch expects an original installation, the original T3UI.ini in particular. Existing tweaks may or may not be compatible.
It's not necessary to install the official 1.1 patch before installing the SU.
Steam users should disable updates for the game and refrain from doing game cache validation, because it would remove the patch. Be sure to run the game once prior to installation, otherwise the game's registry values may not be set. As a work-around to get the overlay working, add the patched game as a non-Steam game. (Browse to the Steam install and select the Thief3.exe file.)
If you have existing savegames, and they appear to have gone missing after installing the patch, then chances are that your SaveGamePath registry value is set to a location in your private user folder. (The original default path is in your Documents folder). Such paths are diverted to the public Documents folder for the unpatched game, but not anymore after patching. Either locate the new folder and move your savegames there, or edit your registry to use the old path. Also note that Thief 3 Gold will use a separate folder for savegames, since original saves are not compatible.
