'''BAMTA''' ('''B'''inary '''A'''udio '''M'''e'''TA''' data), also known as '''BAMETA''' is a file format used on [[Wii U]] games like [[Super Mario Maker]] and [[Nintendo Switch]] games like [[Mario Kart 8 Deluxe]] and ''The Legend of Zelda: Breath of the Wild'', normally included into [[BARS]] files. It contains audio information.

= File Format =
== Header ==
The file starts with a header that is 0x1C bytes long.
