ZX Spectrum emulator for Mac OSX
The latest compiled version and older versions can be downloaded at zxsp homepage.
zxsp runs on Intel Macs with Mac OS X 10.6 "Snow Leopard" and above. Reportedly it also runs well on ARM based Macs with macos 13.1 "Ventura". Latest report is for macos 15.6.1 "Sequoia". So it currently should run on any Mac since 2009.
To compile this project you currently need an old Mac, Mac OS X 10.12 "Sierra" is best, Qt 5.09 to 5.13, Qt Creator 4.10.2, which is the latest version running on Mac OS X 10.12, and possibly a version of my script interpreter vipsi for adding the macos stuff to the app bundle and run the Qt utility macdeployqt on it. But you can also just copy the libraries and resources from an existing zxsp installation. Make shure to checkout the zxsp git archive with submodules, because it contains zasm which in return contains the Libraries.
The code base was messed up around 2014 or so, when i certainly made backups but did not yet use git. Though i added a lot of new features i didn't release a new version because of a number of bugs that i couldn't fix in time.
Currently i'm in the progress of isolating various parts of the source to make them better maintainable. Meanwhile i mostly only do bug fixes.
