I'm playing with some options to make Arcadeflow more suitable for computer games too... the first issue is that most computer games artwork packs don't feature "Wheel" artwork, at least I couldn't find them for Amiga on EmuMovies. This doesn't look good because you'll see a screenshot with the smooth gradient on top. There are two ways to solve this:
1 - When there's no Wheel art, the gradient is not applied, and you can then see the full snapshot
2 - Add a "text caption" instead of the wheel artwork, but that won't probably look very good...
I have coded the first option (see attachment) but I'm still thinking if the second one is better or not...
