hucard, bee-card etc. are all kind of cool and cute for sure. for real carts i like the japanese MD the most, followed by NeoGeo and SFC carts. it seems that the states and Europa always got the most ugly one, regarded to the US SNES, NES and MD carts. either they're blown up unecessary big or got an ugly shapelifting almost equal to their hardware counter parts. generally it's not just the shape itself, also the stickers and boxes etc. coming mostly directly from hell.
