To get the title key decrypt the 16 bytes at offset 0x1bf with the master key using the Title ID (offset 0x1dc) as the initialization vector (the last 8 bytes of the IV should be zero).
 
<b>TO CONFIRM:</b> xt5 has said on HackMii that offset 0x1F1, with a value of 1, is used in Korean Wiis to use a different common key. Can someone confirm/update?
