The Extended Banner format is ridiculously simple. The Extended Banner is used to add text (and optionally an extra texture) to a given banner. It can also (optionally) be used to set an expiration date for a banner.
The Extended Banner format is very simple. The Extended Banner is used to add text (and optionally an extra texture) to a given banner. It can also (optionally) be used to set an expiration date for a banner.
See [[Extdata|here]] for how the extended-banners are loaded from extdata. The Home Menu extended-banner loading function will immediately return without loading anything if the programID is for System Settings.
=== SpotPass ===
When Home Menu loads extended-banners, it also attempts to load a "[[CBMD]]" banner via [[BOSS_Services|SpotPass]] service commands. Normally this CBMD banner doesn't exist in extended-banner extdata. This is [[BOSS_Services|broken]] with New3DS titles since Home Menu uses these BOSS commands with the New3DS bitmask in the programID set. The common and language-specific(when offset is non-zero) "CGFX" specified by the CBMD are decompressed and processed.
The "CGFX" sections in this CBMD are actually the exact same exbanners loaded from normal extdata. The exbanner data from SpotPass is stored to the same state as the extdata-exbanners. No CWAV is loaded from SpotPass data.
The exbanners from SpotPass must have a timestamp less than current_datetime, otherwise they won't be parsed. The timestamp for the banner is calculated with: <code>nintimestamp_mktime(out, exbanner->year, exbanner->month, exbanner->day, <hour=23>, <minute = 59>, <second = 59>, <millisecond = 999>);</code>

The date used for never-expiring exbanners varies, on retail like with Mii Maker this is December 31, 2099, where year is 0x833, month is 0xC, and day is 0x1F. The expiration-timestamp is only used for SpotPass exbanners, not extdata-exbanners.
