So, @Xkeeper found the music frequency tables in Super Mario Bros. 2 a few days ago.
<Xk> Let's see what happens when we swap the values in reverse order.
<Xk> ...
<me> ... oh dear.
Here's what we got:

@Raspberryfloof It does sound nice to me for whatever reason. What do those music frequencies do anyway? Is it the notes in reverse order, but on the regular melody?
@BatElite Pretty much. The game has a list of values that it uses to play each note, ordered in ascending order (C, C#, D, D#, E...). We reversed those values, so they go in descending order (C, B, A#, A, G#...), but left the actual music data untouched, so it uses the wrong values.
@Raspberryfloof @Xkeeper it’s really good with that 1-1 music
@Raspberryfloof @Xkeeper zelda 1 has a similar frequency table (maybe even the same one) ! I remember being confused because the notes are not strictly in order, it's like they added a bunch they thought they would need and then added more for accidentals. I wanted to write a program that pokes the music but…
@Raspberryfloof @Xkeeper oh this is great
Of course, after this, I had to check what other Mario games used this same frequency table.
I found out Super Mario Bros. 3 also did.
It turned out about equally well.
