Libre40: a static-recompilation port of Army of Two: The 40th Day

Libre40 builds a native Windows host for the Xbox 360 release of Army of Two: The 40th Day using ReXGlue static recompilation. Its extraction and code-generation scripts use the player's disc image to produce local game files and recompiled source; the author reports playable single-player gameplay.
