I have the 1541 Ultimate II cartridge for my C64 and it is a fantastic unit. But the C64 itself is getting on and I wonder how much longer it will last. This is very exciting! Does it resolve the C64 Chroma/Luminance interference issue? I would love to get a real hardware implementation of the C64 without the interference flaw and see it on a modern display without the horror colour bleed. I also vaguely remember reading a guide on how to solve the problem on an original C64 with some modification, but I simply cannot find the page anymore. Does anyone have any info on this?
