jplakon/CallOfDuty4_VR ? reverse-engineered prompt

Build me a Windows VR conversion for Call of Duty 4 that lets me play the single player campaign in OpenXR with a headset, stereo view, and full head tracking.

I want the game to feel natural in VR, with motion controller aiming, physical scope support, a VR friendly HUD, and the usual campaign menus and dialogs working properly in headset. Please include a configurator app so users can adjust settings, plus a guided installer and a portable option for people who already have the game installed. It should work with a legitimate copy of the original game and not include any game data.

Make sure the experience is stable across common VR setups, handles controller bindings cleanly, and includes the usual compatibility fixes needed for older COD4 campaign missions and menus. If you need current docs or runtime details, look them up online and iterate until it feels solid.
