Wow, why is this not on the front page?

this is incredible

Skills, no doubt. Also, a cheat mode. Indestructable. That kinda helps.

Um, isn't this an emulator with manually programmed controls like all the other speed runs?

The original game on the NES did not play like this. This is running on an emulator with the code altered.

Yes it did. I've never played the game on emulator, and when I watched the video I thought "that's it?" because I've had nearly every single thing he shows here happen to me on accident at some point in time. Some of them on purpose, because it's an easy way to get coins quickly or reach secrets like "Minus World". Either way, this is not a hack.

haha upvote for that 1-up thing on 8-2

Oh, and it's definitely playing on an emulator, specifically NESticle. You can see the NESticle hand in the last few seconds.

It may be played on an emu, but I too can attest to at least most of that being the original SMB behavior. In fact, for the first few minutes of the video I was wondering what was so special about it other than his precision. The main bug he utilizes is the mis-calculation of collision with ground, which even I've used way back in the day. It's how he jumps from nothing when he's next to a wall, pipe, or brick, how he glides through bricks in the underground areas, and how the turtle gets stuck below the floor. There were a couple tricks I hadn't seen before though, so I'm going to have to go rewatch it, maybe try it out on my NES.

I think you miss the point. It's not that this isn't possible in the original game, it's that the feats of timing are likely programmed as in those once-common speed runs which would get posted. Someone is just having more fun with the technology. Go watch a Zelda 2 speedrun and then try to do it on the NES.
