The Register: "The discovery came a couple of days ago when one poster uncovered a little
adjustment hole at the back of the console which, when tweaked, seemed to act as
a contrast control. IGN then documented the tweak for its readers, which seemed
like a fair thing to do.
But in looking at it now in retrospect, they're probably kicking themselves for not
double and triple-checking with Nintendo on the subject, because as revealed to
the American gaming news service today, the "contrast control" is actually a bit
more sinister."
