I’ve been a huge fan of this game since it first came out, sometimes leaving my Nintendo system on all day while I was at school (there was probably a way to save it but I had no idea) so I wouldn’t miss anything. And I agree that that was just beautiful.
Now, if there was a similar video of someone playing Mario Kart 64 in record time like that, my day would be even better. 
I’m sure he loses a life on the flamethrower bit! At about 6 minutes 1 second.
Well, don’t forget that we don’t know how many attempts he made before getting everything just right. There could have been 50 or a hundred (or even five hundred) times he did get dinged and just sighed, hit RESET, and started over. After all these attempts, he pulled the pristine 11 minutes off the tape and made a grab at geek immortality.
No I’m wrong! Sorry!
I can just hear DK saying “You don’t unnastand. I coulda had class. I coulda been a contender!”
“… I coulda been someone, Mario, instead of a bum, which is what I am, let’s face it. I’m a bum. It was you, Mario.”
Anyway, it’s been a long time since I played Super Mario 3 - could you really jump like that? I couldn’t. 
But I do mean that as a serious question pursuant to cheating. Still some serious skill employed here- this guy isn’t Mario, he’s Neo.
Could he have used an emulator? A lot of them have save/load features. At the very least, he could have saved before the start of each level. The fade-to-black-screen between levels could easily hide video splices. Still an impressive feat, but much less difficult than having to play the whole game perfectly.
cough cough See my previous post.
I’m guessing this may have happened…certainly in the case of the guy going through all 8 worlds of SMB3 as little Mario. At any rate, it’s still insane.
Whoops. Sorry, pulykamell.
Since it seems like nobody knows this guy’s name, it’s not much of an immortality, is it? 
I was a complete Mario Bros junkie. I mastered all three, finishing them all by warping. I then went back, and was able to finish them all by not warping. I have no idea how quickly I finished each game, however. After I did this a few times, the games became boring and I never played them again. I also had no desire to play any of the 64-bit games. This was several years ago.
The 8 worlds video seems false.
There are 2 levels where he double jumps… I don’t remember there being any spots with invisible blocks.
Still, his skill is awesome.
Where are you seeing these double jumps? I haven’t seen any. Are you sure he’s not jumping off a turtle/koopa/etc midway?
His name is at the end of the video. I’m sure his name brand value is picking up some steam (in Japan anyway) 
I watched this a couple days ago, and if I remember the characters correctly, his name is Morimoto.
i skimmed through this and didn’t see an answer, so i shall.
I have a video of a dude beating the Original SMB, and exploiting every bug in the game (save one*). he walks through walls, does fireball tricks that makes it look like hes just killing enemies by touching them, swims through fire arms. does a bunch of edge jumps on ledges, and a bunch of other insane stuff. That video is real, it is recorded off a TV, then at the very end, a nesticle game is loaded and he jumps over the flagpole. That screen is totally different from the rest of the video and must have been added later. Almost all of his tricks i’ve been able to do myself, and everything has been duplicated by others, so he didn’t cheat. The video is called like “SuperGodmode” or something.
*The only thing the guy doesn’t do is the small mario with fireballs.
That video was by far one of the coolest things I’ve ever seen. You have to admire a guy with the tenacity to keep playing until he could do this.
I don’t suppose anyone has a link to the SMB1 exploit video?? I was excellent at this game and knew most every trick; I’d love to see if I missed any.
Do a search on crazygodtechnique.avi
You should be able to find it. I did (yesterday), but I can’t seem to locate which web page it came from.
I take it that he also doesn’t exploit the “infinitely repeating water level” bug?
