This application compiles Z80 assembly language into a format that the Spectrum understands, typically machine code (a binary executable).

  • Download the executable (i.e. from the releases page
  • Open the ZIP file and copy to a folder on your PC (i.e. C:/Tools/sjasmplus)
  • Add this folder to the Path environment variable in Windows System Properties. Make sure you edit the Path in System Variables, not the one in User Variables for Administrator.
  • You *may* need to restart Windows for the path change to take effect. At the least, you will need to close and re-open any Visual Studio Code instance.
  • Open a command prompt.
  • Type in sjasmplus to test.
  • You should be greeted with the sjasmplus help text output in the command prompt.
