this is the 0x20(32 bytes in decimal) byte block that you find at offset 0x9C in a uncompressed theme described here on 3dbrew: http://3dbrew.org/wiki/Home_Menu/Themes#Decompressed_body_LZ.bin_structure
i didn't wrote from what themes are from the values

(but after some testing i found out that this is the right formatting of the bytes)

(looks like the original yata changed only the first 3 bytes)
