nand.bin
BootMii creates a 553649152-byte NAND dump called "nand.bin" on your SD card. It is formatted as:
- 4096 * 64 pages of (2048 + 64) bytes of data + ECC
- A 1024-byte footer with keying information
Specifically, the format is the same as the format of keys.bin.
keys.bin
BootMii used to dump the keys to a separate file from the nand dump. this was later moved to the nand dump itself, but the format stayed the same. it is as following :
typedef struct {
u8 header[256]; // 256 bytes of human-readable information (e.g. "BackupMii v1\nConsole ID: badcafe0"), padded with null bytes
u8 otp[128]; // 128 bytes of OTP data (copied directly from OTP)
u8 padding[128]; // padding
u8 seeprom[256]; // 256 bytes of SEEPROM data (copied directly from OTP)
u8 padding2[256]; // padding
} keys_bin; // size: 0x400 bytes
