Legend of Zelda Famicom Cartridge -- this was the version translated for English release

Metroid Famicom Disk -- Metroid has never done well in Japan, for some crazy reason

Super Mario Brothers 3 for Famicom -- wonder if it did as well in Japan as the rest of the world?

Super Mario Brothers for Famicom -- and here's the first
