Custom Ocarina Songs.

[BlankedOut]

Again, just reposting something I saved, and posted for convenience:

First, to change the notes you have to play to activate the song, go to these addresses:

Minuet of Forest: BA8DA0
Bolero of Fire: BA8DA9
Serande of Water: BA8DB2
Requiem of Spirit: BA8DBB
Nocturne of Shadow: BA8DC4
Prelude to Light: BA8DCD
Saria's Song: BA8DD0
Epona's Song: BA8DDF
Zelda's Lullaby: BA8DE8
Sun's Song: BA8DF1
Song of Time: BA8DFA
Song of Storms: BA8E04
Scarecrow's Song: BA8E0C

The first byte is the number of notes in the song, the rest are the notes, in the order they must be played, except the scarecrow's song, which is just the length. These are the valid values:

A = 00
Down = 01
Right = 02
Left = 03
Up = 04

Credit to Sakura and I for finding this area of ROM and documenting it.

Next, the notes that are (dis)played back to you* can be found here:

Minuet of Forest:BA8120
Bolero of Fire: BA81C0
Serande of Water: BA8260
Requiem of Spirit: BA8300
Nocturne of Shadow: BA83A0
Prelude to Light: BA8440
Saria's Song: BA84E0
Epona's Song: BA8580
Zelda's Lullaby: BA8620
Sun's Song: BA86C0
Song of Time: BA8760
Song of Storms: BA8800

This is a bit more confusing, so I'll use a screenshot.



Highlighted is the Sun's Song. Each row follows this format:

XX00 YYYY ZZZZ AABB

Where X is the value that determines the note, Y is the length of time it's held, Z is the volume, A is pitch, and B is vibrato.

Anyway, here are the valid values for X:

A = 02
Down = 05
Right = 09
Left = 0B
Up = 0E

And it should be noted that both A and B are signed, so no going over 7F unless you want negative. In case you're wondering, this is because both are normally controlled by the control stick, and that of course uses negative and positive values to represent Up / Down and Right / Left.

Highlighted in blue is FF of course, which seems to be a rest of sorts, that also appears to determine the end of the song. I don't know why it has values for volume all things considered, but I would guess that when its duration is set to 0 the song terminates. Could be wrong though, I'll have to do a bit more testing.

Credit goes to Punk7890 for finding this area of ROM, BlooDMooN for identifying pitch, vibrato, and the second volume byte, and myself for documenting the rest.

*In quest status and when you're learning it this determines the actual notes, but when you play it all it does is change the notes that are displayed as the music file for the song is played.

Here's a GS code to edit the Minuet of Forest song... Values are the same as if you
were editing the ROM.

Do you use a hex editor?

Yes.
