A friend of mine back then was actually in touch with US Gold about coding it (and he was one of the few people who'd have been capable of it). But they suddenly changed their mind and said "no, we're not doing it".
Rob Buckley, Radical Software. I was going to be doing the music. But there wasn't really any point doing even homebrew CPC development after AA folded - no-one to sell it to. http://www.cpcwiki.eu/index.php/Lethal_Moves
Do you know if Rob ever released any of those unfinished things?
It looks like some work has been done recently on a port of SF2 to CPC -- I must admit, it's been a decade since I had a working CPC... I would like to get one, but maybe emulating things is best at this point.
