−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.
