Have you ever played a game to the end and then started again immediately after you beat it?
I remember doing that with Super Metroid a couple times. I thought that game was so awesome that, after busting up Mother Brain and escaping, I popped open another file and kept rolling like nothing happened.
I've done it with Bomberman64, too. Actually, that's a game I haven't played in a while. Maybe I'll whip that one out in the near future.
