Super Mario Advance. On the Mario Bros. side, Mario can pick up a POW block with the B button. My brother tried that, and somehow, with a fireball going through him, got ninety-nine lives. Well, with that, we got to phase ninety-nine, which just repeats itself. Well, the same few phases repeat themselves as phase ninety-nine, even the bonus level. Also, after getting 999990 points the points do not get any higher either.
So, there's no real point to continue playing it, with the six lives left, but at least we know where it all ends.
