(MESS) odyssey2: converted the driver to use slot devices for
cartridges, removed The Voice add-on from the main system
and emulated it as a passthru cart instead. Now, if you want to
enjoy speech in odyssey/videopac games, you must launch
emulation with
  mess.exe odyssey2 -cart voice -cart2 gamename
(the -cart2 switch becomes available when "voice" is mounted
in the first cartslot) [Fabio Priuli]
