I don't dare look this up on a work machine, but a google in the general direction of "Steamworks emulator" should get you going. The files in question are modified Steamworks DLLs (x86 and x64), an info file that holds the Steam metadata for the game, and a launcher to read it.

Hrm. DDG shows one (unhelpful) result for that. Google sent me running in circles. Has this emulator been taken down?
