Nestopia CRT monitor simulation

[fenderjaguar]

I've recently been using the artwork that comes with MAME. In particular, "aperture2x4rb" looks fantastic on my 1920x1080 LCD monitor. Does anyone know if there is a way I could overlay this effect with Nestopia, or if there is a different NES emulator this could be achieved with?

Here's a screen shot of Mario Bros 3 on playchoice:
