| The data located here is copied to here by the ARM11 process. The data located here is a TWL NAND [http://dsibrew.org/wiki/Bootloader bootloader] image, using the same format+encryption/verification methods as the DSi NAND bootloader(stage2). The keyX for this bootloader keyslot is initially set to the retail DSi key-data, however when TWL_FIRM is launched this keyX key-data is replaced with a separate keyX. TWL_FIRM can use either the retail DSi bootloader RSA-1024 modulo, or a seperate modulo: normally only the latter is used(the former is only used when loading the image from FS instead of FCRAM).
