Best NES style plugins for FL Studio

Can anyone recommend a good plug-in for FL Studio that allows you to mimic NES sounds? I`ve heard of Tri-Force but hear that Magic 8-Bit Plug-In is quite good too.

Anyone used either of these to good effect? I want the most authentic sound possible.

Any help would be great.

I use this one.

Thanks Amon will give it a try.

OK that works great. Now all that I need is a way to emulate the wobbly note effect (sorry not sure of the musical term) of games like Megaman.

Any suggestions? I need it to be as authentic as possible.
