Files that contain the .z64 file extension are ROM image files that are associated with the Nintendo 64 video game system. A Z64 file contains a copy of a game cartridge that was used with the Nintendo 64 system.
Z64 files allow users to play popular Nintendo 64 games on their computers without the need for the actual Nintendo 64 gaming system or the actual N64 game cartridge. In order to play a .z64 file on a computer, however, a Nintendo 64 emulator must be installed on the user's hard drive. Files with the .z64 file extension are similar to files that are saved with the .n64 file extension.
