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 of that 1024-byte footer is:

  • 256 bytes of human-readable information (e.g. "BackupMii v1\nConsole ID: 0408cafa"), padded with null bytes
  • 128 bytes of OTP data (copied directly from OTP)
  • 128 bytes of padding
  • 256 bytes of SEEPROM data (copied directly from OTP)
  • 256 bytes of padding
