Final Fantasy 3 US
« on: September 25, 2009, 03:59:02 PM »
 :hmm:
So I am trying to figure out how to re-sequence music in FF3us. I am starting by hacking "The Prelude" because it is one of the simpler pieces. Here is what I have figured out so far. PLEASE someone correct me if I have a mistake. I am new at this SPC stuff and need help. Thanks!


Prelude
(085EA0 - 08661D)


086120 (Octave set for Flute track) (default 06)
086121 - (portamento set E4)
086122 - ??? ( 0D )
086123 - Little note before first sustained note (1B)
086124 - First flute note (default 01)
086125 - notelength ? (AC)
086126 - Tempo of flute? (default - AF)
086127 - Silent Note 1 (default B1)
086128 - Silent Note 3 (defaut B3)
086129 - End Portamento (E5)
08612A - Octave down (D8)
08612B - change in note after octave shift - changes length of note too not - doesn't appear to be consistent(9B)
08612C - Octave up (D7)
08612D - change in note after octave shift - changes length of note too not - doesn't appear to be consistent(if this is changed to 9B, it will be exatly one octave higher than the previous note (default - 1D)  
08612E - Octave down (D8)
08612F - Next Portamento(E4)

Update:
So I figured out the pattern for the notes (again focusing on the Flute track in 'The Prelude')

After the first octave drop at offset 08612A (D8), the next 2 hex digits establish the note that is played within that octave. As it stands offset 08612B is set to 9B, which is a B-3 half-note. Changing it to 9A would make it a whole note. Here is a list of the notes:

Half notes:

01 - C
oF - C# / Db
1D - D
2B - D# / Eb
39 - E
47 - F
55 - F# /Gb
63 - G
71 - G #/Ab
7F - A
8D - Bb
9B - B
A9 - C 4
B7 - Rest

Quarter Notes:

04 - C
12 - C# / Db
20 - D
2E - D# / Eb
3C - E
4A - F
58 - F# /Gb
66 - G
74 - G #/Ab
82 - A
90 - Bb
9E - B
AC - C 4
BA - Rest

Eigth Notes:

07 - C
15 - C# / Db
23 - D
31 - D# / Eb
3F - E
4D - F
5B - F# /Gb
69 - G
77 - G #/Ab
85 - A
93 - Bb
A1 - B
AF - C 4
BD - Rest

23 3C  - notes
F2 - end of channel (and in this case the sequence)

This should help if you want to take a peek at MQ/SoM/FF5 imports to FF6.  Now if I could figure out FF4's core a bit more...

*edit*
Oh, and so far a great job on importing FF4's battle theme.

Just an FYI, I found some very valuable FF3 US info from this document on RPG Legion. The VERY bottom of this LONG file has some great info on SPCs, BRRs, and the operators. Check it out if you're interested:

Been there done that years ago.  That document is old, it was originally released with FF3ed. 

Somewhere I have a breakdown of one of FF6's sequences but at the moment I cannot find it.   :lame:

*edit*
Oh and there is also a more complete spc sequence command list around my harddrive too that I cannot find at the moment.

It was helpful getting me started. My FF4 music hack is going very well. I am predicting I will get stuck getting the whole song to loop properly. If I don't figure it out, I will let you know! Thanks for all the great resources. I have big plans for my hack :)

MathOnNapkins did a disassembly of Chrono Trigger's SPC core.

But I think hacking the hex manually is probably clunky. There's another way, but my attempt to explain it didn't work very well.

Well, I've completed putting the FF4 battle theme into FF6/FF3us

Check it out here:

I have already started working on Gilgamesh's theme. Stay tuned for that.

That's awesome! I've always hated the FF6 battle theme -- I had decided that when I started hacking FF6, I wanted to change the battle theme to FF4's. But, I would have had no idea where to start, and now, you've already done it! Great work!

I'd definately like to take a look at the sequence to see how it works.  To see what I did wrong in trying my FF4 conversion. 

Was it coded from scratch or did you try and convert the existing sequence?

I absolutely had to code it from scratch. Once I figured out how FF6's SPC core worked, I used that to essentially re-compose a 'new' song in place of the old battle theme. I will be releasing a patch for each song once I have completed my Eternal Crystals hack.

I don't track well so I wasn't able to sequence any song.  I tried and tried to just convert the existing sequence.  lol

What a pain in the arse... I finally finished Gilgamesh's theme! You can see here:

This song is HUGE bit-wise. I had to replace the "Returners" theme because it actually had the most usable bytes.
I think if I can do this song, I can hack almost any other FF song into FF3/6.
