Here are the general guidelines
.
Japan HuCard:
Jewel Case + Manual + HuCard + Vinyl Sleeve + thin SPONGE FOAM + Registration Card(not sure if all games included foam, but it was used to keep the HuCard in the tray -- a buffer between the HuCard and the manual when the cover was snapped shut. A FEW games (Namco?) had trays with two SHORT plastic HOOKS that were used to hold the HuCard + Sleeve in place... these special sleeves had two holes punched out -- for the hooks).
Comparison of Japanese vs. US packaging, using the same game.TRIVIA: I have 1 or 2 vinyl sleeves that are decorated (i.e. a white concentric swirl is printed on one sleeve). No North American sleeves were decorated.
Japan CD:
Jewel Case + Manual + CD + Spine Card (OBI) + Registration CardExample of Japanese CD packaging, sorry, no comparison to US packaging.North America HuCard (NEC era):
Jewel Case (with plastic arm) + Manual + HuCard + Vinyl Sleeve + Cardboard Box + Styrofoam Insert (since the boxes were bigger than jewel cases, you need the styrofoam... same concept as NES packaging)
Note: As previously mentioned, Keith Courage lacked a plastic arm and had double-sided sticker instead.
North America HuCard (TTi era):
Manual + HuCard + Vinyl Sleeve + Cardboard Box + Clear plastic "tray"(HuCard rested in the middle of the tray, with manual resting on top)
North America CD (NEC era):
Jewel Case + Manual + CD + Cardboard Box + Styrofoam InsertNorth America CD (TTi era):
Jewel Case + Manual + CDBOTTOM LINE: While cardboard boxes were wasteful (trees!), they were seen as a theft deterrent (like the longboxes CDs used to be packaged in). Later, TTi wanted to cut costs, so they revamped the packaging... but for HuCards, I guess it was cheaper for TTi to keep the cardboard boxes and nix the jewel cases.
I've said this before, but the plastic arm in the US jewel cases is a GREAT improvement.
