Heres a Beta Release of an Original Xbox Emulator for Windows, heres the release notes:

Cxbx Reloaded Git (2018/03/13) is compiled. Cxbx-Reloaded is an emulator for running Microsoft Xbox (and eventually, Chihiro) games on Microsoft Windows. The project began life as a fork of Cxbx with added 64-bit support. Work is currently underway to backport some of the improvements from Dxbx. Cxbx-Reloaded is still pretty unstable, don't expect it to run much at this point.

Cxbx Reloaded Git Changelog:
* Merge pull request #983 from PatrickvL/InlineVertexBuffer
* IVB : Select FVF position mask once without overwriting the other FVF bits
* IVB : Renames and refactorings, copied over from WIP_LessVertexPatching.
* Merge pull request #984 from PatrickvL/YUY2
* D3D : Added YUY2 and UYVY conversions, derived from libyuv. Also, added a fallback to ARGB when a first CreateTexture attempt doesn't work
