hey doom,
the Japanese games were shrinkwrapped jewel cases... except for maybe some special packages (i.e. I have a boxed Forgotten Worlds which came with a 3-button pad).
dj898 (i think), has a thread at digitpress with a HuCard packaged in a VHS or DVD case (that's odd, never heard of that before).
in North America:
originally, all games came with box and jewel case and styrofoam.
then, during the TTi era, jewel cases (and styrofoam) were eliminated from hucards.
also, boxes were eliminated from CD games.
there was a thread on this at digitpress ... can't remember when.
