What is an HWAV file?

An HWAV file is an audio file used by 3hs, a homebrew replacement for the Nintendo 3DS hShop. It contains background music that can be played in 3hs. Primarily, gamers create HWAV files by converting .WAV files via an online conversion tool.

More Information

The Nintendo 3DS hShop was an online repository from which gamers could download 3DS games, DLC, apps, and other content. 3hs is a custom replacement for the now-closed hShop, which gamers can install on 3DSes that have been hacked to use custom firmware.

Optionally, 3hs users can choose to play background music in the app. To do so, they must convert one or more audio files to the HWAV format. Then, they must place those files in the following location on their 3DS SD card:


Usually, gamers use 3hs's online HWAV generator to convert WAV files to HWAV files. However, gamers can also use the 3hstool included with 3hs to convert other types of audio files to the HWAV format.
