What are CVZ files and how to open them

What is a CVZ file?

A .CVZ file is a VZ200 Cassette Image file.

VZ200 Cassette Image files store data originally written to magnetic tape cassettes for the VZ-200 (and compatible) home computer machines. These images capture the encoded audio waveform that a VZ-200 cassette recorder or emulator would load at the CLOAD prompt. They are used to replay the exact cassette signal - either digitally in emulators or via audio output for real hardware.

This format is generated and used by emulators such as JVZ200, DSVZ200, and WinVZ300. These programs allow saving or loading programs as cassette images, preserving the signal timing correctly. In practice, the cassette data is stored so that when an emulator plays a CVZ image it simulates what the VZ-200 would hear from the cassette port. These images are also convertible to audio formats for playback into real machines.
