Unified Emulator Format
From Just Solve the File Format Problem
The Unified Emulator Format (UEF) is a format used to store raw tape, disk, and ROM data from Acorn computers, including Kansas City Standard data cassettes, in a computer file suitable for storage and transfer on modern systems and networks. Since some other computer systems (e.g., the SOL-20) also use the Kansas City standard for cassettes, this format will also serve to archive cassette data for them, similarly to how a Tap file encodes Commodore cassettes.
