I discovered a longer version of the 1-up fanfare in Super Mario Bros (NES)

[27/04/2021 EDIT]: Please note that the information and terminology I showed and used back then on the video is not entirely correct! Check the pinned comment for why this sound is actually triggered. There is no such thing as a 'slot that manages the sound'. The HEX editor shown is a live dump of the emulator's RAM, which I randomly manipulated until I presumably changed a variable that kept track of the sound playing.

I'm keeping the video up because a lot of people seem to enjoy this little cool fanfare, but take what I said on the video with a grain of salt!

Edit: It is a slowed down version of the powerup sound and the normal 1-up sound one after the other. Sounds cool imo.

I'm not an expert, so it would be great if someone could explain why happened this ^^

Wow! Two years since this video was uploaded.
A lot of people explained that the 'long' part of the sound was the power up sound slowed down, since apparently they are next to each other in memory. Now, two years later I kinda understand this better since I began studying Computer Science, so ignore some of the stupid assumptions I made back then lol

The notes before the shortened 1up sound are actually the sound of mario eating a mushroom but slowed down and high pitched

0:06 i don't know why but for some reason i love this accidental transition from the ground theme to the underwater theme

[JouvaMoufette]

This isn't unused content, this is other content being used in unintended ways. It's just the mushroom sound played with a different instrument and speed.

Amazing how we are still discovering things 25+ years later

[Burn_Angel]

Now the music is muted.
And I feel sad.

I like how this glitch happens in SMB3 when you tail-whip during a 1-up... The exact same tracks play too. Slowed-down power-up and 1-up, forming a weird extended 1-up track. Very interesting.

Why have I been recommended this 2 years after it has been uploaded
Still Cool discovery well done

0:08 WHAT IS THIS THIS LITTLE SECOND SOUND REALLY GOOD!

[theauggieboygamer]

The bit before the 1up jingle is actually the end of the power up sound effect (easier to hear when you speed it up)

[Sickmmaner]

If you play the video in 2x speed, you can hear that this is actually the mushroom sound, as well as the end flag sound.

[nargishun]

Alright that’s cool and all but are we not gonna talk about how good the overworld theme sounds with long notes? 0:07

[flariz]

Ok but why didnt you make the video 10 minutes long to get extra money?

[NintendoGamer]

I heard this one fanfare happen through a corruption on vinesauce

[thesystem]

When Mario gets 4 1ups all at the same time

[benjaminbrady]

It's more likely to do with the fact that all music data is stored right after eachother and all you're hearing is the level complete sound followed by the normal "extended one up" due to having an incorrect time interval

0:15 I need a full version of the water theme with that instrument (the one that has a little echo)

[otesunki]

ive heard that sound while messing around with game genie codes
kinda cool to know that in both smb1 and smb3 the extended 1up sound is taken from the last notes of the power up sound

[DaniPooo]

Could it be that they use the same sequence for both the victory theme and the 1-up?
Because this sounds like the victory theme in slowmotion with the 1-up in normal speed at the end. This would not be the first time nintendo reuse and speed up/slow down sound samples to save space. I belive this was common in ocarina of time and Mario 64, same trick is also used for pokemon cries.

[TheQuickSlash]

Actually, that’s because of how the game stores it’s sound effects. The Mushroom grow sound and the 1UP are in the same file. Mario 3 also does this
