LibreGrimrock: 64-bit reconstructions of the Legend of Grimrock engines

LibreGrimrock reconstructs the engines of Legend of Grimrock and Legend of Grimrock 2 as native 64-bit C++ modules from their original executables. The work follows recovered compilation units, class layouts and Lua bindings, while adapting platform libraries and loading data from owners' game installations.
