nes emu + pixel refresh

[bill00000]

I've noticed the blur effect when there's too much black and motion, but never as bad as when emulating nes, likely because of the colour palette of the nes. Do you think a "change black to grey" option would fix this? Is there a nes emulator that I can edit the palette in (without knowing crap about coding)?

it might reduce the effect it wont completely fix it though (it happens on colours also)
