80130F38 - cutscene-like mode boolean value

8016B9F9 - Sheik songs (first time you play songs)

0x800EE6F4 to 0x800EE818 - Ocarina playing functions such as: Cutscene-like mode (unable to move when completed a song)

Note/Title rendering (when you're playing a song) 0x800EE790

Note playing 0x800EE758

Note/Song checking

Note checking (play a wrong note and you get a 'ding' sound, like when you're learning a song.)

I think that's it.

800ED5B4 - play 09 note automatically if nopd

8016BA20 - note buffer

80131878 - song to play

T9 - song number?

A2 - song length

V1 - successful matches

0x800ED200 - this function.

@0x800ED2FC - 'note buffer' address; 0x8016BA20

@0x800EE758 - button press function check,

             will play a note if you nop
             some beqs, im sure it's possible
             to play by changing values in ram
             somewhere. just got to look further into
             this.

@0x800ECD80, 0x800ECC94,0x800ECCCC - counts until it starts to check, The game only starts to check what you're playing once you've hit the 5th note!

THE HACK:

Change instruction which clears song value when ocarina is used.

Coincidentally (or not!), T3 already has Epona's song value in it.

So we use it instead of R0 (Which holds zero, always)

.ORG 0x800ECCD4

SB T3, 0x1878(AT)

Instruction which clears song value once ocarina is being used,

we get rid of this so it doesn't happen.
