NES/SNES Synthesizer?

Anything that doesn't fit into other topics goes here!
Does anyone know of a good NES/SNES synthesizer? I know there's a gameboy emulator in LMMS but it's not quite what I'm looking for. I've seen a few online (Not sure if they were the correct format or not since they didn't say anything in the description), but which one is recommended?

I just tried installing it but it doesn't seem to be showing up, do I just have to copy it into my plugins folder or is there something special I have to do?

Edit: Derp, never mind, I should have looked in the VST plugins with VeSTige sooner lol.
