A library and utility for parsing vintage Sphere cassette tape data. The Sphere computer systems could read and write data cassettes in a format that was specific to those machines. Documentation on the format is provided in the SPHERE_FORMAT.md file in this repo.
The library comprises the two files spherecas.c and .h and can be used outside of this program. Information on how to use the library is in the header file.
All the files together build to a sphere2bin tool. No makefile is provided, you can just cc up the files directly:
cc main.c spherecas.c -o sphere2bin
You use the utility by giving it the name of the input tape data. If you supply the --list option, it will only tell you what it finds. If you omit that option, by default the utility will emit a separate .bin file for each "block" it finds within the input. Sphere cassette blocks are named with a two-character value, which will be part of the output filename.
