[quote name='Ye0ldmario']Does anyone have one of these systems? Supposedly it plays super nintendo and regular nintendo games.
are these things some kind of chinese knock off of some sort?[/quote]
Yes that's exactly what they are. Some are better quality than others. Basically, the hardware patents on the NES, SNES, Genesis hardware, controllers etc. and others ran out, so these companies came in and manufactured clones.
I have a black FC Twin, plays every NES and SNES game I've thrown at it. You should be able to get them relatively cheap, like even $20-25 new through various sources...
