I have been in 2nd place in this game for years but I finally was able to get the world record. This run is highly competitive and I’m very happy with this achievement!

I’ll be doing more attempts to try to get a 4:56:XX time.

This run was played on a real NES with an original NES controller. If anything looks unusual to you in this speedrun, look through this list of frequently asked questions:

Q: How did you skip the flag coming down in 1-1? Why didn’t you do that on other levels?

A: This is an old trick but new for humans to be able to pull off. Someone by the name of Sockfolder figured out a somewhat consistent way to do this. It’s hard to do multiple times in one run, but future runs will do it more than once. Watch this video for more information: https://www.youtube.com/watch?v=ucBAwdS3YB4

Q: Why did you not die when you touched the piranha plants?

A: This is an old game and a lot of the enemy hitboxes aren’t in line with the enemy sprites. Look at this picture to see what i mean http://i.imgur.com/DpY0WaS.png

Q: How did the pipe in 4-2 take you to the warp zone? Aren’t you supposed to climb the vine?

A: Jumping backwards into walls changes mario’s position on the screen and tricks the game into sending you to the wrong place. I do a similar thing in the 3rd room of 8-4. For more info: https://www.youtube.com/watch?v=PInZ2-qfKEU&t=42m17s

Q: What did you do at the flagpole in 8-2?

A: This is similar to the glitch I did in 1-1 to skip the flagpole, but even better. Look at this picture for details: http://i.imgur.com/DpY0WaS.png

Q: How did you jump off the pipe in 8-4?

A: By jumping at a very precise spot on the pipe mario will actually stand inside of the pipe for 1/60th of a second, and if you press the jump button during this period of time you will jump. More info on this image: http://i.imgur.com/DpY0WaS.png

Q: How did you not die to bowser’s hammers?

A: Sometimes you simply jump through a gap in the hammers, and sometimes you actually go right through a hammer. This is because the game can’t always handle having all those hammers on screen at once, so some of them don’t have hitboxes.

If you have any other questions feel free to ask in the comments or send me a private message.

Special thanks to Andrewg1990 for paving the way in this game, darbian for pushing the game even more and being very supportive, Sockfolder for finding the setup for flagpole glitch, everyone else who has contributed, and everyone who watches my stream/videos and helps support me. 🙂
