ROM Hack Question Is there any way to hack Pokemon Sword/Shield music properly?

[Dark_Ansem]

The loop points need to be edited. This is found within the bank files in the NX64 folder where the sound is. However, the struct needs to be known first in order to figure it out. I suspect that we need to edit either Init.bnk, or BGM.bnk.

These are files generated by Wwise 2017, so any tool which can edit loop points for files generated by Wwise 2017 should suffice.

See, I was overcomplicating my life by looking at Hex edit

download sound editor 2018 and wwise
then convert any music via wwise, open stream.pck with sound editor and find the music you want to replace.

huh? can it be that simple?

His method is correct. However, this does not allow for seamless songs. The songs will retain the original loop data. This is why we must search for the loop data and fix it.

Thank you for your insights. Do you, by chance, know what encoding would work?

As far as I know, the codec which this Wwise engine uses is Opus. With Sound Editor 2018, the song is seemingly encoded with said codec, allowing it to play in-game. However, I could be wrong.

So in theory another song which works on switch would work?

Not as far as I know. Only songs with the same length in each part would sound seamless.

That is WITHOUT loop points, right?

Yeah. With the stock loop and length data still in the game, any song that has a shorter length than the song you replace will still play at said length (meaning there will be inaudible silence until the length is met), and any song that is longer will be cut off at that point. However, if you manage to cut the song so it loops just like the other song, it should give the same loop effect.

yeah I replaced normal pkmn theme with smt nocturne one but it cuts off the song then loops.

Just from observations I did with PlatinumMaster, the sound system seems to be cobbled together nonsense, as some of the important data you would expect seemingly isn't there (such as loop data, track length, etc.) despite other games using the same system and not having any of these hurdles. It's not the first time Game Freak has programmed something that is more convoluted than it needs to be. I'm expecting, but certainly not hoping, that properly hacking the game's music will require rebuilding the sound system from the ground up.

 

[Dark_Ansem]

rebuilding from ground up?

 

[Dark_Ansem]

So now I finally have my copy, let me dump its entire concents and see what happens.

Aren't songs like the Gym leader theme a bunch of songs that play at different times?

Yes - they change depending on the course of battle.

Another tutorial here BTW: https://gamebanana.com/tuts/13151

 

[Dark_Ansem]

OK, I'm ready but need some help in identifying the various cues of the music. Is there a spreadsheet online of dumped music?

 

[Dark_Ansem]

So, been looking at the music files again - noted that few people have offered to help.
I don't understand if the stadium chorus is actually part of the BGM or a separate audio file.

It is part of the BGM, if you are referring to the Gym Battle BGM.

I believe the dynamic music tracks are separate audio files linked together by a routine. That'd probably be even more of a headache to hack than just normal music.
