== Music ==

The eShop pulls its music from a static, region-specific link in the following format:
 +
 +
https:// a248.e.akamai.net/f/248/103046/10m/npdl.c.app.nintendowifi.net/p01/nsa/CtfKXACbUPl8s7lk/BGM1/REGION_BGM1 ,
 +
where region is one of the primary system regions (JP, US, EU, KR, etc.) Support also exists for 'BGM2', but this seems to be unused.
 +
The music is held in a [[SpotPass|BOSS]] container.
 +
 +
The format consists of a brief XML header describing the audio (including the date it was set as the main eShop theme, loop times, size, etc) followed by a raw AAC stream. Tools such as FFmpeg can handle rebuilding this stream with ADTS headers for proper time info and such.
 +
 +
The [[Home_Menu|Home Menu]] uses nearly the same format for the Theme Shop's background music.
