    Only for Windows?

      The build linked on this page is Windows only. If you would like Mac or Linux you will need to build your own.

    do you have a repo like this: https://github.com/TheGoodDoktor/8BitAnalysers

    but for the CPC-Analyser rather than the spectrum one?

    I’d like to build for linux.

        You beat me to it. 🙂 The CPC version is currently in it’s own branch. It will be merged into master when it’s feature complete compared to the ZX Spectrum version. I’m not far off that point.

        The linux build may not compile out of the box. I don’t have an easy way to build linux here. Once it gets merged into master we will have the luxury of continuous integration which will solve this issue.

        Just to let you know, the code is merged into master now.
