Trolmite

Ah I see, thanks for replying! Hmm seems like no one has tried to make such a version yet, it might be possible I think...?
Yes there does not seem to be one for the atmos or coupe either, interesting!

This is quite a good version overall, incredible how someone pulled this off. It plays pretty close to the speccy version despite being graphically inferior. It is nice on spectrum, though probably better on original hardware. 
Also is there a zx81 version of JSW as well?
