Kevin Manne pointed us to a source port of DOOM that has just been released for the NUON DVD platform (NUON is the name of a chip designed by VM Labs that brings interactive features to DVD players in which it is integrated). Originally used as a technology demo to show how easily games could be ported to NUON, this port is said to have been done over a weekend. Currently, it runs the shareware doom1.wad file, but it should be possible to add additional .wad files in the future. The source code will also be released shortly. More information, screenshots along with a zip file can be found here.
