0x4 u16 Byte-order mark
0x6 u8 Unknown (unused) [check]

Usage in Breath of the Wild


This resource is found in Bootup.pack.

Its canonical resource path is "Sound/LoopAssetList.blal".

A standard loop asset list can be found in Sound/. It is loaded in Sound::init (called from ksys::InitializeApp) and afterwards only used indirectly by SoundLink.
