The blob is TWLCFG bytes 0x88-0x1AF, HWINFO_N bytes 0x88-0x9B and HWINFO_S bytes 0x88-0x9F, copied to 0x02000400, 0x02000600 and 0x02FFFD68 when a DSi title starts. Without it the same bytes are read from shared1/TWLCFG0.dat or TWLCFG1.dat (the higher save count at byte 0x81) and sys/HWINFO_N.dat and sys/HWINFO_S.dat of an attached NAND, generated for DSiWare run without a NAND, and left zero in card mode."
