It is Spectrum +2 and loading with divIDE.
Thanks for looking into it.
I think it has issues with +2. I remember someone mentioning another older game was not working correctly with their +2. Maybe try emulation and see if that works better as you can select the model. I think it's fine with a basic 128k machine. Not sure about +3. Unfortunately I believe it's an AGD problem so not much I can do to fix it.
