Freelancer.Reverse.Runtime: reconstructing the game's dacom.dll interface

Freelancer.Reverse.Runtime reconstructs part of Freelancer (2003)'s runtime DLL interface through a compatible dacom.dll proxy. The proxy loads the original module, forwards exports, and logs calls associated with hashing, string comparison, telemetry, and initialization; the author reports using it in a running game.
