Ok, right the problem is there is no way to associate a module with
display head within MythTV.  However, in this specific case,  maybe
it's possible to hack the XML code (gamelist.xml and modify the
<command/> content) for MythGame to include something like the display
and head name? After all, the game emulators are just plain X11 apps
and they should respond appropriately to the -display option.
