Downloading ROM data of classic games is a very VERY gray area (for some reason). I'm guessing since Nintendo's coming out with that plug n' play NES console that they'll crack down on various emulation sites.
But that sucks. This whole lawsuit thing has to be part of some troll's menacing scheme to ridicule Nintendo fans who pay tribute to their favorite franchises. For whatever reason I can't imagine the executives working at Nintendo being that selfish (since they're obviously not lawyers). Whoever's doing this is no different from the playground bully who takes your drawing of Mario and rips it into pieces for their own enjoyment.
