A legal, unmodified and DRM-free copy of Amnesia: The Dark Descent is required.
This is atrim, a custom client for Amnesia: The Dark Descent which attempts to port the game to very old and weak machines, and make it compatible with operating systems as early as Windows 2000.
The client is based on version 1.4.3 of the game and it also brings out new enhancements and features from Amnesia: A Machine for Pigs, as well as fixes and improvements to bugs and glitches in the game and engine.
For retail DVD users: Please make sure that your copy is updated to Version 1.3.1.
If you're unsure which version of Amnesia: The Dark Descent you currently have:
- Check the hpl.log file (found in your %USERPROFILE%\Documents\Amnesia\Main folder), or
- Check with the seller or storefront of the copy you purchased the game from.
Alternatively, you can download an archive of the 1.3.1 patch, which bundles the 1.0.1, 1.2, 1.3 and 1.3.1 updates for you all in one package.

Steam users should already have the Version 1.5 update. GOG.com, Epic Games Store and other storefronts have the 1.4.3 (1.41b) patch. There is no need to download the 1.3.1 update since most storefronts will update the game to the latest version that Frictional Games officially provides.
