Call of Duty 2: Big Red One: a native loader for the Xbox game

Call of Duty 2: Big Red One runs on Linux and Windows through a native loader that maps the original Xbox x86 game code into a PC process and replaces Xbox platform services. Parts of the renderer, sound system and game code are rewritten as source, with function names grounded in Ghidra analysis and rewritten functions checked against the original through a comparison harness.
