Thanks for the suggestions but I'd class these more alongside R-Type. They tend to overlay one object over another totally and resort to black square edges where background detail goes missing. Karnov seems to be compositing the pixel detail of the background layer and the sprites, and uses a mask so I think the techniques are quite different. Depending on the specific colours in a given clash, sometimes the background colour wins, sometimes it's the sprite colour, and I think that really works well to minimize the impact of the clash.TomD wrote: ↑Sat Feb 01, 2020 9:18 am Try Dan Dare 3 https://spectrumcomputing.co.uk/index.p ... 96&id=1241 and Savage https://spectrumcomputing.co.uk/index.p ... 96&id=4353
See this example of what I mean - notice the background pixel detail remains in the colour clash around his arms:
