== Nintendo Wii ==
The Nintendo Wii stores a small amount of data here; some of it is Wii-specific (such as NAND keys), but the hash of the version of boot1 used in that Wii is also stored (making boot1 impossible to update), and the common key used in the Wii.
=== OTP Contents ===
The following things are stored inside the OTP:
