What is a Z81 file?

A .Z81 file is an EightyOne Snapshot file.

A snapshot file, also known as a save state, is a saved representation of the current state of the emulator, including the contents of memory, registers, and other emulator data. Snapshot files allow users to save their progress in an emulator and resume at a later time.

Some pros of the .z81 file format include the following:

  • Allows users to save and resume their progress in the emulator software
  • Small file size, making it easy to store and share
  • It can be used with a variety of Sinclair ZX81 emulator software programs
