XBMC4Xbox is a free and open source media player software made solely for the first-generation Xbox video-game console.

Since the XBMC4Xbox is homebrew software that is not endorsed or supported by Microsoft in any way, it means XBMC4Xbox requires a modchip or softmod exploit installed to run on the Xbox game-console.

[17][18] XBMC4Xbox does also just like XBMC feature; audio visualizations, slideshows, weather forecasts reporting, and a Python-based API for third-party plugins.

Accordingly, unofficial executable builds from the subversion repository are often released by third parties on sites unaffiliated with the XBMC4Xbox project.

This collaboration began in December 2005 and came to fruition in January 2006 by successfully integrating the Team Xored Trainer Engine into XBMC4Xbox.

XBMC4Xbox can run trainers with the following file extensions: *.ETM and *.XBTF[15] XBMC4Xbox previously had an XLink Kai front-end integrated to control that client, but that has been removed in more recent builds.

The first core, dubbed "DVDPlayer", is XBMC's in-house developed video-playback core with support for DVD-Video movies and is based on libmpeg2 and libmad for MPEG decoding yet FFmpeg for media-container demuxing, splitting, as well as decoding other audio formats.

[19] One relatively unusual feature of this DVD-player core is the capability to on-the-fly pause and play DVD-Video movies that are stored in ISO and IMG DVD-images or DVD-Video (IFO/VOB/BUP) images (even directly from uncompressed RAR and ZIP archives), from either local harddrive storage or network-share storage.

XBMC4Xbox is a software application programmed in C++, XBMC4Xbox uses Microsoft DirectX multimedia framework and Direct3D rendering, (as the Xbox does not support OpenGL).

[15] Also required to compile (and program in) XBMC4Xbox is the older Microsoft Visual Studio .NET version 7.1[14] According to Microsoft, it is a common misconception that the Xbox uses a modified Windows 2000 kernel, instead they claim that the Xbox operating system was built from scratch but implements a subset of Windows APIs.

Lack of interest from the XBMC developers got to a point where a new home was needed for the Xbox codebase, and in 2010 it was moved to SourceForge.

A new community site had already been set up at xbmc4xbox.org and was chosen to replace the forums on xbmc.org where XboxX discussion was no longer relevant, as xbmc.org only deals with the platforms that they actively develop.

Accordingly, code compiled with an unauthorized copy of the Xbox Development Kit may not be legally distributed by anyone other than Microsoft.
