Cartridge

From Styleguide

cartridge

A game stored on hardware contained inside a plastic casing.

Do not confuse with cassettes and floppy disks which house magnetic tape.

Unlike cassettes and disks, videogame cartridges generally have no moving parts.

The abbreviated cart is considered jargon.

Example: The Xbox 360 version of Quake 4had load times that were long enough to make most critics nostalgic for the days of quick-loading cartridges.

Wrong: ROM cartridge.

Also see: cartridge-based.
