I think there is some confusion here. Retroelectronik's scanline generator doesn't depend upon a line doubler or a flicker fixer per se. As the name implies, it generates scanlines when inserted in between VGA chained equipment. Since your CD32 is fitted with VGA output thanks to Edu Ananas I mean Edu Arana device (sorry, couldn't help it, ananas meaning pineapple in French) and possibly some other expansion you didn't mention (to get RGB output, namely), it is actually a good candidate for that device. Now the question is does the scanlines themselves seem pretty / consistent to you, and does the price seems right ? To make things clear, it doesn't care if it conveys the signal of a console, a raspberry, a cyborg kangaroo, it just adds scanlines to the picture for any VGA enabled device
. No hiccup during gameplay, no input lag, no nothing, just those "artificial" scanlines you're seeing
, thin or big. Trust your own eyes if you don't trust me!
