Game Pak

Game Pak is the brand name for ROM cartridges designed by Nintendo for some of their earlier video game systems. The "Game Pak" moniker was coined by Nintendo of America's marketing manager Gail Tilden.^[1][2] It was used in North America, Europe, Oceania, and South Korea.  In Japan, Nintendo uses the term Cassette (カセット, Kasetto) when referring to Famicom, Super Famicom and Nintendo 64 game paks, and Cartridge (カートリッジ, Kātorijji) for the Game Boy line and Virtual Boy.

Game Paks were used as the primary storage medium for the Nintendo Entertainment System, Super Nintendo Entertainment System, Nintendo 64, and all models of the Game Boy. The release of the GameCube marked a shift to optical media. While all models of the Nintendo DS, which used Game Cards, were released alongside the GameCube, Wii, and Wii U, which all used optical discs, Nintendo returned to cartridges on a mainline console with the Nintendo Switch.
