Changed layout to organize better, added some more details
Offset 0x00000000 is considered as the start of the partition.

===== Encrypted =====
Partition data is encrypted using a key, which can be obtained from the partition header and the master key. The actual partition data starts at offset 0x20000 in the partition, and it is formatted in "clusters" of size 0x8000 (32k). Each one of these blocks consists of 0x400 bytes of encrypted SHA-1 hash data, followed by 0x7C00 bytes of encrypted user data. The 0x400 bytes SHA-1 data is encrypted using AES-128-CBC, with the partition key and a null (all zeroes) IV. Clusters are aggregated into subgroups of 8 clusters, and 8 subgroups are aggregated into one group of 64 clusters. The plaintext format is as follows:

To decrypt the user data at 0x0400-0x7FFF, again use the partition key, but this time take the IV from bytes 0x3D0-0x3DF in the '''encrypted''' SHA-1 block.

===== Decrypted =====
Once the Partition Data is decrypted, it follows the same formatting as a Gamecube disc for the most part.
