What is a .BNVIB file?
A .BNVIB file is a special kind of file used by the controllers for the Nintendo Switch, like the Joy-Cons and Pro Controllers. These files are important because they contain a type of audio that, when played by the controllers, creates vibrations. This is part of what makes playing games on the Nintendo Switch feel more real, as these vibrations can simulate different sensations, like the feeling of marbles rolling around in a box or the clicks of turning a lock.
This cool feature is called HD Rumble, and it uses advanced technology to make the vibrations feel very precise and lifelike. The Nintendo Switch games have these .BNVIB files built into them, and when you're playing a game, the Switch sends these files to the controllers to make them vibrate at the right times.
Each .BNVIB file is pretty small and has a specific format to make sure it works correctly with the controllers. They're not really meant to be opened or changed by players, so most people who play Nintendo Switch games won't ever see or use these files directly. However, some tech-savvy folks who like to modify their Switch systems, known as modders, have figured out how to make new .BNVIB files or use existing ones in different ways. They can do this using a special program called the Joy-Con Toolkit.
In summary, .BNVIB files are behind-the-scenes helpers that make the Nintendo Switch gaming experience more immersive with realistic vibrations. While regular players won't interact with these files, they play a crucial role in how the Switch's controllers work.
