[Python 3.12.3](https://www.python.org/downloads/) or newer installed.  
Python 3 Module pydub `pip install pydub`  

### Supported Audio Formats

| Audio Format  | NS1           | PS4           | WIIU3         | Nijiiro       |
| ------------- | ------------- | ------------- | ------------- | ------------- |
| WAV (PCM)     | ✅           | ✅            | ✅            | ✅           |
| BNSF (IS14)   | ✅           | ✅            | ❓            | ✅           |
| Nintendo OPUS | ✅           | ❌            | ❌            | ❌           |
| Nintendo IDSP | ✅           | ❌            | ✅            | ✅           |
| Sony AT9      | ❌           | ✅            | ❌            | ❌           |

### Known Limitations
It seems that if a IS14 BNSF .nus3bank file is too long/too large in size, then it'll fail to play in "Song Select", even if the "Preview Point" is properly set.

When it comes to Song ID:  
Nijiiro can have Song IDs ranging from 3 to 8 characters.  
Wii U, PS4 and NS1 can only have Song IDs ranging from 3 to 6 characters.  
Exceeding this will result in an error.
