| This isn't really useful due to [[BOSS_Services#Custom_SpotPass_content|this]].
+
| After successfully loading [[Extended_Banner|extended-banner]] data(done when selecting an icon), Home Menu attempts to load "[[CBMD]]" data into a 0x100000-byte heap buffer from the [[BOSS_Services|stored]] SpotPass content. When successful and the magic-number is CBMD, Home Menu then decompresses the exbanner sections into another fixed-size heap buffer, without checking the outsize at all. The main CBMD CGFX code with ExeFS checks the size, but this code doesn't(however this is exbanner "CBMD", not a "normal" CBMD).
