Sounds made-up. Until someone can confirm how to replicate it, I'm not buying it.

We've all had those once in a lifetime glitches with dusty NES carts, but this just seems too elaborate.

My best Bubble Glitch was during a two player game, Baron Von Bubbla came after me and I tried to dodge, but he eventually nailed me. When he disappeared, he left a white blob on the screen. It just a glitch, but my friend and I were convinced it was the key to some super secret warp or something.

I also did the small Fire Mario trick in SMB one day before school. I showed my brother, but no one else would be believe that it happened and none of us could replicate it because our timing sucked. Years later I found out it was a semi-famous trick and that the legendary Minus World was for real.

Don't feel bad DarkMaze, I've never been able to do the infinite lives trick without using emulator save states to cheat and try over and over.

Small Fire Mario works like this... Get to Bowser as Super Mario. Jump over Bowser and stand by the axe. This works best in earlier levels before he's throwing hammers. As Bowser approaches you, jump up so that you hit Bowser and the axe at the same time. If you've done it right, Mario will flicker as though he's been hit and you'll hear the shrinking sound. However, you will not actually shrink.

In the next level, the first power-up box you hit will have a Magic Mushroom in it. Grab and you will shrink. Hit a second power-up box and a fire flower will be inside. Grab it and you will change to into small Fire Mario. It's pretty cool. There's no animation for small Mario throwing a fireball, so everytime you throw one, you will morph into Super Mario for a split second. One hit will kill you.
