Harrison Electronics Mr. Backup Z64

Summary

The Mr. Backup Z64 is a copying device for the Nintendo 64. The console is placed on the device and connected through its cartridge slot. The Z64 reads the entire contents of a game cartridge and stores them on a 100 MB Zip disk in its built-in drive, from which the games can then be launched. It can also back up cartridge save data, and its BIOS can be reflashed.

Officially sold as a backup device, the Z64 also served developers as an inexpensive alternative to Nintendo’s official development system. Its .z64 images later became a common format for N64 emulators. The collection also includes an RGB-modified Nintendo 64 used together with the Mr. Backup Z64.
