Homebrew [Tutorial] How to make BGM.bcstm files for 3DS Themes

[Ricken]

why is there a 3.3 MB limit?

 

[Ricken]

The max file size of the bcstm must be 3.371.008 bytes (or 3.3MB)

o. my. gawd. no wonder my music has been HORRID in quality XD. i thought the WAV had to be >3.3MB

Thanks. Alot. lol. (maybe i should fix all my bgm.bcstm's ive uploaded? XD)

FYI, 3,371,008 bytes = 3,292 KB = 3.21 MB, not 3.3.

not sure if 1,000...
or 1,024...

I tested it with a file that was 3.28 MB. It didn't work. So probably the standard value of 1024.

I've had some problems with the WAV files when I tried to loop some songs. I actually used a 16 bit 44.1K WAV file and it failed; when the window for BTRSM import popped up, I was stuck with a 9 second track.

It was not until I converted the original MP3 to a WAV file with specific requirements such as 141 kb/s and most importantly I changed from 44.1K to 48K. Ran flawlessly from then on.

can someone tell me what's wrong with my bgm it'll play to the end but once it's at the end it'll keep making the same sound over and over until it loops back to the beginning. if u need the file pm me and i'll upload it to mega. Thanks

Now if someone could just write a script to turn an Mp3 into just that file to save lazy people like me the time and energy.

The BSTRM Converter is now called Looping Audio converter, and can turn any wav, mp3, flac, etc into a BCSTM directly! No need for that secondary conversion tool anymore.

When I use a song (in wav format) and go through BB and BRSTM2BCSTM, it works perfect. The problem is that songs under at least 30 seconds double to twice their size as a brstm and loop, even though I unselected loop. I don't want them to loop, as they are just fanfare. But they keep looping until the new timespan is over. Any way to fix this and not have these short files loop? For example, I start with a 3 second wav file. I DON'T loop it in BrawlBox, then I use BRSTM2BCSTM. However, the new bcstm file is now 12 seconds long and it loops! I just want the 3 seconds without looping it.

 

[gryz]

Can anyone help me on how to make a non-looping BCSTM file? Like the short ones on brawl custom music. Those ones don't loop... How do they do that? I've been using this program for a while, and I still can't figure out why my file always comes out as a looping BCSTM. Can I just hex-edit it manually to achieve the non-looping effect? If so, please tell me how to do that!

Every day we see people who ask questions in the Tutorial section...
But I've never seen someone who posts a Tutorial in the questions section. [It might as well be such seeing the content here nowadays, no offense devs]

 

[Jayro]

I wanna know how to make a loop, I can't figure it out since this tutorial is so outdated.

I personally do all my converting with YATA+ (other than MP3 to WAV)
Within YATA+ there's a converter which lets you go right from WAV to bcstm and add a loop during the process, which is quite simple once you see the UI

Thanks, this helps tremendously.

Do you know of any .bcstm music players for computer? I'm ROM hacking FE13 and trying to figure out what song is which is a NIGHTMARE, so I'm wondering if there's a program you know of that can play these files. I can't find one, but I figured I might as well ask.

You would probably be best making a jenky body_LZ for Usagi, and renaming each music file to bgm.bcstm then running the body_LZ in Usagi

Or you could do this on a missive scale by seeing how many .bcstms there all, making a folder, then making numbered subfolders to match the amount of bcstms there are, in each one put any body_LZ, then put a different bcstm in each of the folders, renaming (to bgm.bcstm) as you open them, then naming each subfolder after testing so you can easily find them later

Will likely take a while, but so does A9LH

Is this "Usagi" a program that I haven't heard of?
Or are you referring to the character in FE14?
And, there's a LOT OF THEM. AT LEAST 50.

Usagi is a 3DS custom theme maker... but it can play "bgm.bcstm" files along with themes (body_LZ.bin)
Unless there is a program that simply plays bcstm files I haven't heard of

Cheers, this helped.

Hello gbatemp this is a simple tut for those who are stuck or don't know where to begin.


Question- Im not hearing anything what did I do wrong?
Answer - Make sure you have Background Music checked for your theme in the Theme Editor.

Hi First I would like to thank the op for making a tutorial!! I want to report what seems to be a be a bug for Yata+ Version 1.8
I couldnt find the flag "enable BGM" at first, even though I scrolled to the very bottom of theme settings. However, when I enlarged the window, "enable BGM" appears at the very bottom.

Hope this helps with ppl struggling to find where "enable BGM" is.
