CXBX

CXBX is not a typical emulator. Rather than emulating the Xbox hardware, it converts an Xbox executable into a working Windows program. That sounds far-fetched, but it is possible because the Xbox’s architecture is so close to that of a Windows PC: Microsoft drew heavily on its experience with Windows when designing the Xbox.

Compatibility is poor. Most games refuse to work, and those that do are extremely slow or full of bugs. Even so, CXBX was one of the more promising early attempts to run Xbox games on other platforms. Development of the original CXBX stopped long ago; its work was continued by the Cxbx-Reloaded project, and xemu is now the most compatible Xbox emulator.

Note: CXBX was designed before 64-bit Windows became mainstream and may not run at all on 64-bit systems.
