Wasn't sure where to put this. I asked AnotherGamer where I should post it so blame him if this isn't the thread I should have posted it in. :P
Anyway, this is a play through of Super Mario Bros where I've adjusted the value for speed (0057) to 67...which is the highest speed I could get without the game being forced to wrap around itself...heh. I tried playing with the value adjusted to 127, which is the the highest speed attainable by Mario. But the game kept wrapping around itself and I eventually land in a endless loop when I pass the "real" flagpole.
If you don't want to mess with the emulator or just don't know how to cheat in FCEU, I also uploaded this to youtube. Can be found here:

A few notes: I'm not trying to break any records with this! It was just for fun! That's why I didn't try to be an idiot and submit it. Heh. I had to warp to world 5 because I couldn't get the exit to appear right. With this cheat I am forced right at all times. So I go to 5-1 and finish from there. Other than that, just enjoy what mayhem comes of it.
Finally, feel free to make another such run, man I'd love to see what kinds of things come from super speed!
