[SOLVED] Pokémon Black and White - Assigning different Trainer Music

Oxnite · April 26, 2012

When you're spotted by another Trainer, you hear a certain kind of music.

For example, when an Ace Trainer or Veteran Trainer has spotted you, this music's being played:

And when you are about to battle a Psychic, you hear this strange music:

http://www.youtube.com/watch?v=HTFbRZT-HCs

The encounter music is determined by the Trainer Class you are about to battle. If you are about to battle a Psychic with an Ace Trainer's overworld sprite, you still hear the Psychic's encounter music.

tl;dr

Is there a way to edit the encounter music and assign a different encounter music to a certain Trainer Class?

------------------------------------------------------------------------------------------------------------------------------------------------

Additional information

For example, I am going to add the Aroma Lady Trainer Class in my hack. Therefore, I am replacing an old Trainer Class, the Baker. But I want a different encounter music because I find the ''Parasol Lady'' music better for the Aroma Lady:

In other words, can I assign the Parasol Lady encounter music to the Baker's Trainer Class?

if you mean changing sound on NPC? you can using :

Method 1 : go to http://projectpokemon.org/forums/showthread.php?21005-B-W-Champion-Music (changing some hex value on SDat, using crystaltile and hex editor) actually is same because all sound is stored on sdat except for pokemon musical.

Method 2 : ...

Oxnite · May 1, 2012

Thanks a lot for your reply, Andibad, but I already found something else. Actually thanks to elementking, who taught me that the arm9.bin file is compressed. By decompressing it, I found very valuable hex data.

So in the decompressed arm9.bin file, I actually found data for the encounter music. The offset is, exactly, 0xA35C8.

The first line is as follows:

02 00 5A 04 03 00 5B 04 04 00 5A 04 05 00 5B 04 32 00 5D 04

02 00 means Trainer Class 2 (which is the Youngster).

5A 04 corresponds with the different Trainer Class music versions. 5A 04 is the Youngster, joyful encounter music: ''EYE1''.

The following is a complete list with Encounter music, in combination with their hex numbers:

045A

Youngster

045B

Lass

045C

Twins

045D

Ace Trainer

045E

Roughneck

045F

Parasol Lady

0460

Cyclist

0461

Psychic

0462

Scientist

0463

Harlequin

0464

Hiker

0465

Clerk

0466

Gentleman

0467

If you look at the third and fourth hex digits, it shows the following.

03 00 means Trainer Class 3 (which is the Lass).
5B 04 corresponds with ''EYE2''.

Which is true.

Even more:

32 00 means Trainer Class 50 (which is the Male Ace Trainer).
5D 04 corresponds with ''EYE4''.

Which is true again.

I checked EVERY Trainer Class this way and it works like this everytime. For example, Trainer Class 23 00, which is the Psychic (Male) Trainer Class, has 04 61 = EYE8 encounter music. This again is true. In other words, this must be the correct data. The narc even says field_sound_system at the top of this data.

HOWEVER! Here's the problem that I would like some help with.

When I change a certain number (either the Trainer Class number or the corresponding ''EYE'' music number), literally nothing happens. I really don't know what I'm doing wrong. It could possibly be the way I insert / extract (decompress / compress) the arm9.bin file. Though I'm pretty sure I do it the correct way.

Could anybody somehow test this?.. Or does anybody know what I am doing wrong? Or whether there could be anything else I have to change? I really doubt it because this data is so.. obviously right.

Yes you right. But i think is have missing step (last i touch arm9.bin, i was done to recompress them correctly and replace is seems correct, after i test it is nothing but another problem i was break arm9 ). Is another method and seems you try change id trainer on *.bin . For now i can't help you about edit arm and overllay stuff, i no have time to do or prepare them because my brain was mixed with my midtest is very very hard

And sorry i can't help you maybe mid july i get my time

PS: and your new beta is make me relax a while , and you have time to teach me something i can't? For arm9 and overllay i was know about them and thank you for you explain but i was know about that. Yeah swarming pokemon too on that part. I using CUE for compressing and dscemp for decompressing.

So in other words, arm9.bin always .. breaks when you try to recompress it? Could that be causing the problems?

And could you maybe tell me the offset for the Swarm Pokémon?

supagokuman2 · June 4, 2012

i inserted my own song to the rival battle, but it stops after a while and the battle is just mute. Do you know how to fix that?

Kaphotics · June 4, 2012

you have to loop it.

supagokuman2 · June 4, 2012

How do I loop it?

Plus, the song is a bit slow.

On another song I also did it has long pauses.

Kaphotics · June 4, 2012

this thread is about assigning different pre-existing music to a trainer, not assigning new music.

there's a few guides on how to loop sseq's (I know pokecommunity has one), so look there; change the bpm in your midi editor (fl studio etc)

supagokuman2 · June 4, 2012

You're right, and I have successfully looped it, but it's missing some instruments and at parts slows down/speeds up, or plays the same note for a long period of time.

If you can help, PM me.

ON-TOPIC:

That music that plays as an encounter is th EYE files, right?

you don't need to recompress it. just put it back in. MIi_UncompressBackwards() just won't do anything when it goes to decompress the arm9 on booting. it should work.

e: btw, i just did the disassembly. this is a lookup table of trainer ids and music that is accessed by the subroutine at 2029E38. the function takes the id of the trainer and uses that to look up what music matches that. interesting little routine.

The solution has been found, with great thanks to Bond697!

This is what I asked him:

Hi, Bond697!
Thanks for your information in this topic: http://projectpokemon.org/forums/showthread.php?22308-Pok%E9mon-Black-and-White-Assigning-different-Trainer-Music

However, I still can't get it to work.

Are you saying that I should decompress the original arm9.bin file (by using ''Extract'' in CrystalTile2), then edit it by using a hex editor, and then add it to the .nds file again using CrystalTile2's ''Import'' function? This means that I'm adding an uncompressed file that's bigger than the original arm9.bin (because it's uncompressed this time). Is that OK? And what should I do when this message shows up?

I tried editing the following part (it's the encounter music information, starting at 0xA35C8 of arm9.bin):
02 00 5A 04 03 00 5B 04 04 00 5A 04 05 00 5B 04 32 00 5D 04 31 00 5D 04 46 00 5D 04 47 00 5D 04 19 00 5D 04 18 00 5D 04 12 00 5F 04 11 00 5A 04 2E 00 62 04 34 00 62 04 2A 00 5B 04 29 00 5A 04 4B 00 66 04 4C 00 66 04 33 00 61 04 40 00 61 04 3C 00 63 04 3B 00 63 04 1D 00 64 04 5B 00 60 04 5A 00 60 04 55 00 5F 04 54 00 60 04 06 00 64 04 49 00 64 04 35 00 64 04 07 00 64 04 2B 00 65 04 2C 00 65 04 1A 00 65 04 22 00 65 04 0D 00 5F 04 42 00 65 04 30 00 5F 04 43 00 65 04 3A 00 65 04 1B 00 64 04 1C 00 64 04 3D 00 65 04 3E 00 65 04 23 00 61 04 24 00 61 04 53 00 65 04 39 00 5E 04 48 00 61 04 1F 00 5E 04 1E 00 63 04 20 00 63 04 21 00 66 04 56 00 65 04 57 00 66 04 41 00 5F 04 4A 00 64 04 10 00 5C 04 3F 00 5E 04 44 00 63 04 45 00 63 04 27 00 67 04 4D 00 67 04 2D 00 64 04 0F 00 5C 04 0E 00 5C 04 08 00 65 04 09 00 65 04
The red aligned part holds information for the Black Belt Trainer Class. 33 00 is the id of the Black Belt trainer; 61 04 correctly corresponds with
. Say I want Black Belts to have the Gentleman's encounter music. Then I'd have to change 61 04 to 66 04, right? (Because 66 04 corresponds with
). However, that's what I did but the Black Belt still has its own encounter music.

What am I doing wrong..?

(...)

The solution is very simple. It turns out that inserting the arm9.bin file into the rom using CrystalTile2 method doesn't work (at least, for me). Therefore, you should use this method:

use dsbuff and unpack the rom. decompress the arm9 however(or use ct2 to extract a decompressed copy). change the stuff you want like you said and repack the rom with dsbuff.

DSBuff just repacks the entire rom (without the need of replacing the arm9.bin file).

Thank you very much for your help, again, Bond697!
