DSi/3DS Skins - Custom SFX


TWiLight Menu++ supports custom sound files in themes. Place your sound files under the sound subdirectory in your theme folder, for example for the white theme, you would place the files at themes/white/sound/sfx.bin and themes/white/sound/bgm.pcm.raw respectively. Both files are optional, if bmg.pcm.raw is missing, the default music will be used. The same thing would happen with the sound effects if sfx.bin is missing as well.

Dessa instruktioner förutsätter att du har devkitPro installerat med mmutil. Du kan skaffa devkitPro på devkitPro-webbplatsen.

Ljudeffekter #

The sound effect bank (sfx.bin) contains sound effects such as the icon select sound, etc.

Fil Beskrivning
startup.wav Spelas vid uppstart. Se avsnittet om Uppstartsljud för mer information
back.wav Tillbaka
launch.wav Spelas när du startar ett spel
select.wav Played when moving the cursor in the per-game settings and select menu
wrong.wav Spelas när du når slutet av sidan
switch.wav Spelas vid byte av sidor
stop.wav Spelas på DSi Temat när markören slutar flytta

All the files listed above are required to build a custom sound effect bank. If you want a sound to be mute, you can use a silent audio file. The .wav format is mandatory and the encoding must be PCM.

To build the sound effect bank you need to download this file and put it next to all the .wav files that will be used. After all the files are on the same folder, open your terminal (or command line if you are using Windows), change the current directory (cd) to the folder where Makefile is, and then run the make command.

You will get a resulting sfx.bin file that can be copied to the sound subfolder in your theme folder. This file must be under 512000B = 512 kB. Any file larger than that will result in either crashes or some sounds not playing fully.

Uppstartsljud #

While the other sound effects will work with any WAV file with PCM encoding, the startup sound must be in a specific format in order to work properly, otherwise there will be a gap between when the startup sound stops and the background music begins.

The startup.wav file must be 16-bit 16 kHz. You can use Audacity for example to convert to this format. Once the file is loaded in Audacity, change the Project Rate (Hz) to 16000, then press Shift+M, and change the Format to 16-bit PCM.

If your file is in Stereo, you should also go to Tracks > Mix > Mix Stereo down to Mono.

You must set PlayStartupJingle=1 in your theme.ini for the startup jingle to play.

Meny BGM #

Menu BGM needs to be a 16-bit 16 kHz Mono raw PCM file. Below are two methods for converting audio files into that format.

Unlike sfx.bin, bgm.pcm.raw can be arbitrarily large.

ffmpeg #

The simplest way to convert music for use in TWiLight Menu++ is to run this ffmpeg command in a terminal:

ffmpeg -i [inmatningsfil] -f s16le -acodec pcm_s16le -ac 1 -ar 16k bgm.pcm.raw

Replace [input file] with the name of the file you want to convert. You can usually do this by simply dragging the file onto the terminal window with the cursor in the correct location.

Audacity #

If you don’t want to use the command line you can also convert using Audacity.

To convert the audio:

  1. Ladda filen i Audacity
  2. Om din fil är i stereo, klicka på låten och välj sedan Tracks > Mix > Mix Stereo down to Mono
  3. Ändra Project Rate (Hz) längst ned till vänster till 16000

To export in the correct format:

  1. Välj File > Export > Export Audio...
  2. Ställ in File Type till Other uncompressed files
  3. Ställ in Header till RAW (header-less)
  4. Ställ in Encoding till Signed 16-bit PCM
  5. Ställ in utdatanamnet till bgm.pcm.raw och klicka Save
  6. Klicka på OK för att redigera metadata

Now you have a bgm.pcm.raw file that can be copied to the sound subfolder in your theme folder.

You should then set the DSi/3DS Theme Music option in TWiLight Menu++ settings to “Theme” for your custom BGM to play on the menu.
