BodyCache.bin and BgmCache.bin contain cached theme data for the currently used DLC theme. ThemeManage.bin is loaded by Home Menu during startup. The cached theme data is loaded at startup when a DLC theme is selected. This also contains [[SpotPass]] [[News_Services|notifications]] for themes.
BodyCache.bin and BgmCache.bin are all-zero when no theme is selected.
When no theme is actually used, the u32 stored at offset 0x0 in ThemeManage.bin is value 0x1, with offset 0x10 u32 set to value 0x1 too. BodyCache.bin and BgmCache.bin are all-zero here when no theme is selected.
