A series of research and experiments to make a custom map compile and load on Half-Life 2 Half-Life 2 (Xbox).


What we know

  • BSP files from the Xbox game disc load on old engine builds of HL2
  • The compile switch needed for VBSP: -xbox.

What we don't know

  • Texture names: they differ between HL2 Xbox and PC, so BSPs from Xbox are full of missing textures.
  • If Xbox BSPs work on PC, do PC BSPs work on Xbox?
  • How to make old versions of VBSP, VVIS and VRAD not crash constantly on modern operating systems and PC hardware

We have a version of Source SDK dated December 2004, it has been able to compile maps for Source 2004. Compiled maps have been tested in builds 2153 and 2547. I am attempting to contact User:AndrewNeo to see what he knows about Xbox compiling.

The 2004 version of VBSP does not contain the -xbox parameter. This parameter still lies in the source code, but modern leaks such as CSGO will not create the correct version of BSP that we need, even if we did re-enable the parameter. The 2004 version of the SDK we have is from version 2 of sourcesdk.gcf, dated 12/01/2004; and we need version 15, dated 12/31/2005.

Version 16 of Depot 211 was the January 17, 2006 update to Source SDK, which added HDR compile abilities for use with HL2 Lost Coast. This update broke -xbox.
