Aren't there a bunch of knock-off systems coming out of Asia these days? I thought I saw a box that could be play NES, SNES and Genesis original cartridges down at my local games shop.

IIRC these clones may not be able to play all games - especially ones with add-on chips (Super Mario RPG is the only example I can think of right now)
