NOTE:

Once loaded, click past the splash screen and you should be in the "model" section.

*NOTE: .bch files are Smash 3DS character texture files, while .mbn files are Smash 3DS model files!* ​

Music is located outside of the 'data' directory of the Smash 3DS files. Find it in the "sound" folder. Sound files in Smash 3DS are formatted as .nus3bank, and any VGM from Smash Custom Sounds can be downloaded in this format. Simply download nus3bank music off Smash Custom Sounds and replace tracks from the game to your liking. Soneek is working on a way to expand this limit and allow us to add music without replacing, and removing the 2 track-limit on stages.

To create custom SFX, begin by opening the "Sound" folder in my pack. There is a notepad text file inside. Open this and copy the link into your browser. Unzip the file received from this link and place the .exe file inside "Smash IDSP Build".

We will use an example here. Suppose you want to replace the voice clip of Marth's down-taunt. You would need to locate the nus3bank for it in the data folder, which would be \data\sound\vc\snd_vc_Marth.nus3bank. Copy this file (the file of your choice, don't mind the example) and place it in the "injection & extraction" folder.

Open the "injection & extraction" folder. You will see two Python scripts here. One for extraction, one for injection. Hold shift and right click to open the command prompt. Use the following command: nus3bank.py [NAME OF FILE].nus3bank

A folder containing extracted .idsp files will be created in the injection & extraction folder. Inside, find the file you want to use. For example, with Marth's voice clips, if I wanted to change the down taunt sound, I'd locate "0xa-snd_vc_Marth_Appeal01.idsp". Take note of the ID. In this case, it's 0xa.

Take the .wav file you wish to use and place it in the "Smash IDSP Build" folder. Drag and drop it on the .bat file in the folder. An IDSP file of the .wav will be created.

Now, you can inject the custom SFX. Move the IDSP file to the "injection & extraction" folder, along with your .nus3bank of choice.

Hold shift and right click to open the command prompt. Use the following command: nus3inject.py [NAME OF FILE].nus3bank [NAME OF FILE].idsp [ID]
