DKC Atlas Forum

You remember what SMW could do, import custom music using instruments from SMW, well I found this really old japanese hack of DKC, it had custom music, its called SDK mex, I found it here : http://u12.getuploader.com/tyutyuten/do ... dk_mex.zip

Don't worry, it's a IPS...

Of course most of the music hacking stuff is not compatible with the (U) ROM files, so i'm not sure if you could do the same with the (U) ROM.

It's probably possible, the japanese and english ROMs are pretty much the same. I'd like to put Krematoa Koncerto into my DKC hack for its Lost World located behind Kongo Jungle (The extra Donkey Kong head behind Kongo Jungle doesn't really lead there as there is no Lost World in the original game, only in my hack but it will take some time so Necky Nutmare will only be in Chimp Caverns like in the GBC port for its beta release) There are some differences between those ROMs but I'm sure it's possible for custom music to be in the (U) version as well. But then again, I'm new to hacking the DKC games so I'm just making a guess.

Anything the SNES can do is possible when you're hacking a ROM. The question that should be asked is, "How?"

Here are my notes on the music/sound format in the DKC trilogy:


And here's a patch showing that it can be done:
Apply this to a Donkey Kong Country (U) (V1.0) ROM. The file name of the patch tells what it does.

One of the songs I've been interested to hear in the form of an SNES edition is this one:

You're saying, you can recreate it for the SNES?

Yes, it should be possible.

(After reading the sentence above, if anyone is thinking about asking me the question "Will you do it for me?" my answer is no. If I started taking requests, they would never cease and I would be buried in a pile of them.)

Technically, the SNES equivalent is "Voices of the Temple", but if you mean in that actual style, then that'd be awesome.

I always thought of it as some kind of dance/rock tune.

Update!

I am researching with DKC1, 2, and 3 music editing, I'm trying to find out about how the instruments work, and I'm learning ASM on the side.

Jesus christ and people call these games simple what the hell :p

Music hacking can be easy, given the right set of tools, but what amazes me is how thorough Mattrizzles documentation is. Documenting music data has always (to me, at least) been very difficult.
I've dealt with Super Mario Land's music format in the past, and even though the Game Boy only has four channels, I never finished the documentation. Making notes (heh) is easy when comparing changes in the ROM after you've edited graphics/tilemaps/physmaps, because upon testing you can literally see the changes you did. When it comes to editing music, I find it extremely tedious to 'hear' the changes. What byte controls the note's length or octave is somewhat easy, but echo, right/left channel, pitch bend? Come on!
Maybe I just have a bad note ear

To be honest, some of the notes I have related to the music format were lifted from the Japanese documents that Markster linked to in the original post. I just ran them through Google's (sloppy) translator, and tried my best to figure out what the translation said.

The original link appears to be down now, but fortunately, I still have the documents and patches!

In order to view these properly, you need a text editor that can render text using Shift-JIS encoding. Notepad++ can do this.

Also, this SNES SPC700 Player is invaluable when you're trying to see how the code being executed by the sound processor is represented in hexadecimal. It has seven different information displays, which can be accessed by double clicking on the main area of the window when an SPC file is playing. It has other useful features as well, such as the ability to adjust the tempo and pitch.

Not by me... but is interesing...

I am trying to change the music and sound around in the game. I translated this bit from the doc Mattrizzle posted.

In addition to this, the waveform set system is used.
This is the one that reads the specified waveform into ARAM.
There is one waveform set for each song.
The pointer to the waveform set starts at 0x0AB212. It is specified only in the lower 2 bytes.
The most significant byte is fixed at 0x0A.
For song number 00, it is "0xB286", in which case the waveform set starts at 0x0AB286.

I searched for the 86b2 pointer / address but it didn't find any. Any ideas?
Thanks.

Loveemu did amazing work! I heavily used his documentation to create the music here!

How would I go about changing Crank's music with a different one?

and good work sprinklez

Mattrizzle would you be willing to help me out?

That should be fairly easy: just swapping tracks. An array of songs to play by level code is here:
int MUSICTRACK = 0xb983b6;
Actually, for what you describe that might be harder. Changing LEVELS will work as I said. Kong family might be a bit different.

Yes. I knew about that pointer table. It was missing some songs, like the kong family songs? There was no pointer in the table for Cranky's and the kongs songs.
But I figured it out. thanks to MAttrizzle again for the help!
