Notes

  • xboxkrnlce.exe and .hvdata can be found in the Flash folder of a Backwards Compat game's XVC. Version 17003 has leaked publicly.
  • The emulated Xbox 360 does not display a serial number.
  • If a BC Game is deployed in Dev Mode, the XDK's Xbox Console Manager (The GDK dropped this functionality) can be used to capture kernel debug logging from the emulated kernel, when launching the game from the Console Manager.

Discovery

XEO3, known as emu.exe, was first located by TitleOS who dumped it from a plaintext XVDP of eratools captured from a Xbox Live update before releasing it via Twitter.

XEO3 Shaders

Little is currently known about the XEO3 shader format, for example how the original shaders from Xbox 360 games are converted into the DirectX 11 Durango format. While it is known that that Backwards Compat games' XVCs contain DirectX 11 Durango format shaders in the DLL file format, creation or rendering of these shaders is not currently possible.

These shaders appear critical to running any graphical xex, as evidenced by attempting to run XeXMenu on the emulator.
