The actual on-screen resolution is fixed, but this seems to have very
little to do with the actual games.  Some of them look like crap, with
big, blocky, chunky graphics, and others look pretty decent, especially
considering that I can see the actual pixels on screen from as far away
as the controller cables reach.  Yes, I'm completely clueless WRT to
game consoles, there are some in the house now for the first time ever. 
I've played all of 5 hours on them, before I decided that reading mail
on this list was a far better waste, err, use, of my time.  :-)
