Hi, I have ported Defender and Demon Transcendence to CPC - you can grab a copy now from itch.
I still have more work to do to make them ‘better’ Defender needs more optimising but it just became playable - but not fantastic. Demon Transcendence is a good port except the graphics suck. I tried both Mode 1 and 0, what can I say?
Both games are coded in NTC BASIC with inline assembler optimisations.
