For anyone interested in doing the work, there are parts of other
Sigma Designs EM86xx source in the wild as well:

 * http://mvixcommunity.com//showtopic.php?tid/363/fbb_session_id/47f9e0f5a7d0b343adbfbb65039f5206/
 * http://www.geocities.com/em8620l/
 * http://moviebeam.wikispaces.com/page/view/home/15317189
 * which has pointers to several other places, especially

The first one appears to have a replacement development environment
since Sigma Designs SDK isn't widely available.  I believe that a
backup copy of that development environment is here:
http://amd.co.at/anti/hd-player/programming/ (browse around other
directories - there are other interesting sources there as well).

Lastly, while I'm doing a brain dump on this topic, there is also a
large collection of random STB related stuff at - but most of it appears to be for VIA-based
