A ROM cartridge, also simply referred to as a cartridge or cart, is the storage device in which many of the Pokémon games have been contained.
Throughout the Pokémon game series, all of the core series games have been stored on ROM cartridges, with many variances between them. Many side games have also been on cartridge but some have been for the GameCube and Wii (on discs, not cartridges). The ROM cartridges for the Game Boy, Game Boy Color, Game Boy Advance, and Nintendo 64 are officially called Game Paks, while Nintendo DS and Nintendo 3DS ROM cartridges are officially called Game Cards.
