All of the hashes stored in this NCCH header are over the cleartext data. The ExeFS/RomFS superblock starts at offset 0x0 in the ExeFS/RomFS, and the size is specified by the hash region fields.

As of [[5.0.0-11]] the application [[ExeFS]]:/.logo can be loaded from the plaintext region between the access descriptor and the plain region, all applications built since [[5.0.0-11]] ~~likely~~ store the logo here. Normally the size of this logo 0x2000-bytes.

As of [[5.0.0-11]] the application [[ExeFS]]:/.logo can be loaded from the plaintext region between the access descriptor and the plain region, all applications built since [[5.0.0-11]] store the logo here. Normally the size of this logo 0x2000-bytes.

The plain region mainly contains tags for each SDK library used when building the CXI. The version used for the "FIRMWARE" tag is the kernel/FIRM [[Configuration_Memory|version]], this version can also be stored in the exheader "kernel release version" ARM11 kernel descriptor field.
