DSi / 3DS skins - Custom SFX
TWiLightMenu 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/sound/bgm.pcm.raw
respectively. Both files are optional, if one is missing the default music will be used. You should then also set the music option in settings to “Theme”.
These instructions assume you have devkitPro installed with mmutil. You can get devkitPro at the devkitPro website.
Sound Effect Bank #
The sound effect bank contains sound effects such as the icon select sound, etc.
File | Description |
---|---|
startup.wav | Played on startup. See the section on Startup sound for more details |
back.wav | Back |
launch.wav | Played when launching a game |
select.wav | Played when moving the select cursor |
wrong.wav | Played when reaching the end of the page |
switch.wav | Played when switching pages |
stop.wav | Played on the DSi Theme when the select cursor stops moving |
bgm.pcm.raw | Not part of the soundbank. See the section on Menu BGM for more details |
You can then run make
to make the sound effect bank. All files listed above, except bgm.pcm.raw are required, but you can make them silent.
Your resulting sfx.bin must be under 512000B = 512KB. Any larger will result in either crashes or some sounds not playing fully.
Startup sound #
While the other sound effects will work with any WAV file, 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 16kHz. 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.
Menu BGM #
Menu BGM needs to be a 16-bit 16kHz Mono raw PCM file. 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.
To export in the correct format, do:
- Select
File
>Export
>Export Audio...
- Set
File Type
toOther uncompressed files
- Set
Header
toRAW (header-less)
- Set
Encoding
toSigned 16-bit PCM
- Set the output name to
bgm.pcm.raw
and clickSave
- Click
OK
to the metadata editing
Now you have a bgm.pcm.raw
file that can be copied to the sound subfolder in your theme folder.
Unlike sfx.bin, bgm.pcm.raw can be arbitrarily large.
